Populating Fresh Data
Im building a live web chat using php, mysql, javascript, ajax I am fine with sending and retreiving data in real time using ajax as the transfer protocol However, my problem, which is becoming a nightmare, is how to I display it !! Lets say the below is the chat screen,
<div id="messages"> Jamie - Hello Peter = Hi Jamie = Nice Day Peter = I know </div>
Lets say Jamie's next message is "What are you doing today". I can send that off to the database no problem and I can get peters live chat to pull that message in, however, how do I get it to display underneath Peter = I know
As a practice I was using
document.getelementbyid('messages').innerHTML = document.getelementbyid('messages').innerHTML + "<BR>What are you doing today"
That works, but, lets just say the chat gets to 1000 lines, for each new message those 1000 lines have to be pulled out via javascript, a new line written to it and then printed back in the div
Im not sure but I'd take a good guess at this not being optimal and will cause CPU load on the users machine
What is the best way to do this! Chat messages are deleted after 1 minute, but that doesnt matter because by then they have already been sent the the users chat. Just incase you are thinking of completely repopulating there chat with every message they have sent since the chat started..

Submit Vs. A Fresh Page Load
I'm developing a page - mostly for the learning experience - that includes a form with several text fields and a submit button. When it's submitted, there is some server-side processing and the output is displayed as part of the same page. (the form's action attribute is set to: "<?php $PHP_SELF ?>"). One of the steps in the PHP script is to check for the existance of a hidden element in the form so that I know whether the page is being sent out as a result of a new request or from the form having been submitted. This all works as expected. When the page is sent out as a result of having been requested from its "home" page, the results are not shown; when the submit button is clicked, the page is sent out with the results shown. Finally my question: when viewing the page with the results shown, if I press <F5> or click on "Refresh", it behaves as if I had clicked the Submit button (that is, it shows the results). I would expect it to return the page as if it was a new request (and NOT show the results).
Loading Page Fresh (without Cashe)
I have a Database driven site, and I use some tricky url parsing stuff out of a file called index.php3. Now depending on where the user comes from, the url will remain the same, but the header info will be different.
How Do I Force A FRESH RELOAD Of A Page
I've built a few php scripts, but since its reloading the same page I can't get it to refresh the page. I've implemented some expire meta tag...but is there anyway I can try and force it to refresh?
Populating A Select Box
What I want to do for members of my website is to allow them to click a button that will add their name to a list that populates a select box. I can do this on my own, but I was curious if I have to use a database in order for this to be possible.
Populating Two Combo Boxes
I have one combo box (Category) which is populated by a MySQL table using php. I am trying to use the onchange javascript to submit the value selected so that I can populate the other combo box (sub-category) based on what was previously choosen. So can anybody give me a clue on how to submit the first boxes value so that the second can see what was selected (javascript function).
Populating Dropdown List
I am wanting to know how to populate the <SELECT> dropdown menu with all existing values from the DB and also have the value associated with that id selected. This is an updating area of my admin. Any ideas? Here's the code so far. At the moment it only retrieves the value assigned to that id. PHP Code:
Populating A Drop Down Menu
How would I go about populating a Drop Down menu from data in MySQL? If you can show me wither a URL to learn this, or if you feel like telling me here, that would be great.
Dymanic Populating Checkboxes
i like to retrieve a value from DB, accordingly i like to display the checkbox, either checked or not. Now im able to retrieve the value from DB, i can show even show the checkbox, but i cant make it checked???? the Code i used to display as follows, #Require the database class require_once('../dbinfoinc.php'); #Get an array containing the resulting record $query = "SELECT * FROM event"; $result = mysql_query($query); $num=mysql_numrows($result); mysql_close(); $i=0; while ($i < $num) { if(($i % 2) == 0) { $c = '"TableDetail"' } else { $c = '"TableDetail2"' } $event_id=mysql_result($result,$i,"event_id"); $event_name=mysql_result($result,$i,"event_name"); $event_publish=mysql_result($result,$i,"publish"); // if(($event_publish) == 0) { $event_publish = 'No' } // else { $event_publish = 'YES' } $take_action = 'Delete' echo "<tr> <td Class='navText' align='center' class=$c>$event_id</td> <td class='navText' class=$c>$event_name</td> <td class='navText' align='center' class=$c><input type='checkbox' name='publish' if($event_publish==1){'CHECKED'}?></td> <td class='navText' align='center' class=$c><a href='delete_event.php?event_id=$event_id'>$take_action</a></td></tr>"; $i++; } ?>
Re-populating A Form If Errors
I am learning php. I have created a simple Web page with a form. After receing the POST request, I do some error checking. In case of errors, I would like to re-post the page, but with the current values for each field. I have organized my files like this: 1) Webpage with the form (all in html, form action points to a php file) 2) php file that receives the request.
Populating Form Text Box.
I have a PHP form for entering data on-line into a mySQL table.. Because of the intended search facility, I require one field in the form to be completed with exact and precise item names and spelling. In testing, I had achieved this with look-up tables. Ideally I would like the selected item from one of five drop-down lists to autopopulate the form text field when selected. Alternatively at least the option of copy and paste. Copy and paste - for some reason will not work. Autofill worked fine on a test form with no database connection and in standard HTML and javascript, however, once the PHP is added to the page neither method works. Could anyone please point me in the direction of how to get the autofill to work?
Populating A Select Box From A Database
I have a subscription database that allows you to edit a subscribers data. For example, you enter a search term like "Bob" and it returns a list of everyone named Bob. You click the one you want and it goes to a subscriber detail page, where all of his data is populated to a form. You can directly edit this form and click save to overwrite it. The only issue is the select boxes (drop downs) - say I have four options in the drop down box, red, blue, green and black. On my details page for bob I end up with five, I have those four PLUS whatever was saved for his color, so it shows up twice. If Bob is green, my select box looks like: Green Red Blue Green Black How can I make it so that Green only shows up once?
Populating Drop Down And Table
I have a database with the following fields. Name | Company | Date values in each column could be repeated, or not. as in there could be several same names with the same company with different dates, or different names with same company. How do I populate a table with this info and have drop down boxes, so that I can narrow down the search? For example: Name | Company | Date 12 | 1 | 1929 13 | 1 | 1929 14 | 1 | 1929 12 | 2 | 1929 12 | 4 | 1929 13 | 1 | 1941 12 | 6 | 1929 So if in the drop down I select '12' under name, only those entries with 12 are shown, and then I can further sort it by selecting only '1' under Company. Hope I'm clear, I manage to complicate things when I post them.
Populating An Auto_increament Attribute
I have just designed a BD. there are companies with auto increament which are integer. When I try to populate it after i tool value from another form and try to insert it into a table i recieve an error! I don't ask the companyID value from user as it is auto increament.

Auto Populating A Drop Down Box
Basically I'm setting up a website which needs an populated drop down box made up from all fields in a specific column of a table in a mysql db.... Here's the code I've made up using various tutorials.... <?php $user = ""; $host = "" $password = "" $dbName = "" /* make connection to database */ mysql_connect($host, $user, $password) OR DIE( "Unable to connect to database"); mysql_select_db($dbName); //did you forget this line? $sql = "SELECT model FROM usedVehicles"; $query = mysql_query($sql) or die(mysql_error() . "<br>$sql"); //use the or die(...) part ONLY IN DEVELOPMENT ?> <form action="action" method="post"> <select name="option"> <?php while ($row = mysql_fetch_array($result)) { echo "<option value="" . $row['model'] . "">" . $row['model'] . "</option> "; } ?> </select> <input type="submit"> </form> I've left out the connection details for obvious reasons... When I upload and try to test this, jus a blank drop down appears... there are definately fields in the column as I have tried the query on phpMyAdmin.
Reading Directories, Populating Select Box
Can anybody tell me how to read through a directory, get the file names and populate a select box(pulldown menu) with these names? I know how to loop through a directory using something like this: while ($files = readdir($handle)) { $ext=substr($file,-4); if ($files != "." && $files != ".." && $ext == ".php") { do some wild and crazy stuff here; } } It's the populating the select box (pulldown menu) while doing this that I need the help on.
Populating Form Item From SQL Enum Set Rev#2
$sql = "SHOW COLUMNS FROM table LIKE 'subject' "; $qry = mysql_query($sql) or die("Query not valid: " . mysql_error()); $res = mysql_fetch_object($qry); // This returns a row with a field 'Type' containing 'enum(...)' $res->Type = str_replace('enum('', '', $res->Type); $res->Type = str_replace('')', '', $res->Type); //now the string is something like this: one','two','three $temp = explode('','',$res->Type); //temp is an array with as much elements as the enum while ($temp) print array_pop($temp); This way is much more easier using the elements since they are elements of an array. Cleaver isn't it?
Populating Array With Mysql Results
I'm returning a result set of one field in a table, and want to populate an array with the results. I can't for the life of me figure out a simple way to do this without using mysql_fetch_array() to cycle through the results, append that to a var, then explode that into a var and pass that. PHP Code:
Populating A Form Wth Database Info
I've coded a piece of code which populates a form with data read from the database: $connection=mysql_connec ("localhost", "f2821842", "f2821842"); $result=mysql_select_db("QUERIES"); $query=mysql_query("Select * from Emp_Details where emp_num = '$employnum'"); while($row=mysql_fetch_array($query)) {$empname=$row['emp_name'];} <form name="webregform" action="webadmin2.php" method="post"> <input name="requiredname" type="text" size="30" value="<?php echo "$empname"; ?>"> </form> When I echo the $requiredname, I get spaces and no data, and I know that $empname is not a space-it does read a value in a database. 1. How can I get $requiredname to print a value?
Populating Dynamically Generated TextFields
If one assigns something to the value iattribute off an input /text field, that value will be displayed when the form is loaded. My problem is, when building a form dynamically, the only way I can get the text to show is by doing the above, however, as this is an update form, when the form POSTS to processUpdate.php, both the data entered by the user AND the data in the value attribute are inserted/updated. So, how does one dynamically build a form where the data is displayed in the text fields but value atttribute is not set. PHP Code:
Populating Form Fields With Variables
The script itself works fine: mail gets sent. If there are any missing fields the form displays again with a list of the missing fields, but I can't get the form fields of the reloaded form to be populated with teh existing values. PHP Code:
Populating DHTML Menu From MySQL

Populating Arrays From MySQL Query
I have the following code: http://pastebin.com/746601 The field 'material' in 'is_material' contains multiple values for each record in 'is_details'. Because of this I have used 'is_material_lookup' as a reference lookup table containing the 'style_code' and 'material_code' which refer to their full details in the respective tables. Currently I have got the script outputting all the details and one material then in the next block of data, repeating the details with a different material. What I would like to achieve is having 1 block of data with a list of all materials in that, instead of the repeat, but sadly I can't know exactly how to do it.
Populating Dropdown With Mysql Entries

Populating Table With Text File
My web hosting service uses phpMyAdmin and at the bottom of the screen iis an area where I can upload a text file to populate a table. I have a table named groups with two fields: groups_idauto-increment primary groups_name So how do I create my text file to populate this table? I'm going to use MS Notepad. If it's set to auto-increment, do I need to include the number? If so, does it start at 0 (zero)? Would the file look like: 0,students 1,faculty 2, staff or just students faculty staff
PHP Not Populating Form Variables Passed Through POST Or GET
I"m running: Windows Xp SP2 Apache2 PHP5 MySQL4 Everything seems fine and dandy, and I can do scripting on server side, but for some reason I cannot get data from a form to be put into a variable. I have a simple form in an html page which submits, and in the php script that handles the input, none of the data in the form is going into the variables. My php.ini file does have all the GPC's in place(ie variable_order, the way they get processed).
Auto Populating Multiple Drop Downs.
im trying to create two dropdowns, i need the first one to be the category and the second one to be the subcategory. The category drop down autopopulates with the correct info from the database. and uses the table "category", the value of each drop down is represented by the "cat" field in the table (cat is basically and integer id number) and "Category" is used as what the user actually sees in the drop down (category is the actual word of the category). Once the category is selected i would like to have the sub category auto populate with everything that has the same values as the selected category (cat) Here is a break down of how the tables work. Table 1 Name: "category" Fields for Table 1: "cat" (the id number), "category" ( the actual name of the category) Table 2 Name: "subcategory" Fields for Table 2: "cat" (corresponds with the cat id from table 1 to pull the correct data), "subc" (the basic id of the subcategory), "subcat" the actual name of the subcategory. so the way i see it, have a normal drop down populated by a php query. then on change, populate subcategory drop down where cat = cat and display sub category.
Populating The Drop Down And Pressing The Submit Button
1. The first is I have two drop down menus. The first is "year" and the second is "mfr". When a user selects a year from the drop down it then populates the second drop down, mfr, from the MySQL database. Theat is working fine. But the problem I am having is the "submit" button (which I have labeled as "browse"). When I click it. Nothing happens, no action tacks place. I have looked over the code and I can't figure it out. (See Code Box 1 Below). 2. Right now the "mfr" drop down is populated by the MySQL database and reads with a list like "Acr", "Alp", etc. These are abreviations. I need to set up an array to have them instead read the entire mfr name. Example: Instead of "Acr" it needs to be "Acura". Instead of "Alp" it needs to be "Alpine". I need these full names to appear in the drop down. I know I need to do something like this (See Code Box 2 Below) but I can't get my finger on it. Code:
Populating City,state,country Drop Down Menu

Populating Form From Database, Then Passing Results To Next Page
I have a multiple select input in a form that's being populated by a row from my database as such: <input type="checkbox" name="subm[]" value="$row[ID]"> That part is working fine as I can check the displayed page using View Source and see that the value is the correct row number from the database. It is then being submitted on a form by $_POST method to another page where I want to evaluate the checkboxes and display the contents of the entire row that corresponds to each value="$row[ID]" that have been checked. But I can't seem to get it to work. I'm having a problem passing the selected value. Can someone point me in the right direction? $query = ("SELECT * FROM `table`"); $result = mysql_query($query); print "<p>Data for Selections:"; print "<table border=2><tr><th>You chose:"; foreach ($_POST['subm'] as $value) { print "<tr><td>"; print "$row[ID]; "; print mysql_field_name($result, 1) . ": " . $row[name]."<br>"; print mysql_field_name($result, 2) . ": " . $row[address]."<br>"; print mysql_field_name($result, 3) . ": " . $row[city]."<br>"; print "</td></tr>"; print "</table> "; } if (!isset($_POST['subm'])){ print "<p>No matching entry "; } mysql_close();
Populating SELECT Multiple Form Field And Inserting Into Db

Then allow the user to update their selections and update the database. But I can't get my form to work. First problem, I can't get the SELECT field on the form to show the categories, and then I don't know where to go from there. Below are my form page and my processing page. Code:
Dynamically Populating Listboxes Based On Previous Selection
How do I populate the second listbox in this form based on the selection of the first listbox? The first listbox is populated by this query: $year_query = "SELECT distinct year FROM bench_data"; The second listbox should essentially be populated by this: $industry_query = "SELECT distinct comp_desc FROM comp_desc, benc_data where $_POST['year']=bench_data.year and bench_data.comp_key=comp_desc.comp_key"; I know this is alot to ask, but please EXPLAIN the code. I am new and need the explanation elucidated and not just supplied code that will accomplish the goal. Code:

If someone could please help it would be appreciated.
Comparing Form Data To Mysql Data
Im interested in building a script that would take form data, a variable like an address, and compare it with a known address in a mysql table (called addresses), then if there is a match log the address information in a separate table called (addresslog), and return the visitor to a certain page. If there is no match between the address entered in the form and known addresses then the information is still logged into the addresslog database but the visitor will be sent to a different page. I'm still new to this, and am working through the logic and the syntax, but I believe I'm close. It's still not working, I have all of the proper tables, maybe I'm way off with the coding so I thought I would seek out some expert advice. Here's the entire script with as much explanation as I could give. PHP Code:

Data Mining / Data/Website Scraping
I'm looking for a piece of software or coding that will let me post a form to another URL, accept the response, search it for a specific "success" string and then let me continue processing the rest of my program. I want to accept queries on behalf of my supplier, forward it to them behind the scenes, accept their response and display it within my website. Has anyone had any experience with this? Is there a simple, basic utility to let me do this? I was kind of hoping I could avoid developing it myself.

Comparing Database Data And New Data
I am trying to create a PHP script that reads in a file, parses it for the data I want and compares it to the data I have in a database. The data is points and ranking information for a Folding@Home Team. Every week someone creates a news item with points gained by each team member for that week and other info. This is done manually and takes a lot of time. I hope for my script to automate as much of it as possible. The script was to run as follows: Download and parse latest statistics into 2D array Compare usernames in array to usernames held in Database Any new usernames and their respective points/rank to be added to database Compare points in 2D array of each user to those held in database. Output username and points gained I thought I had a working script until I actually tested it on real data, and realised I missed something rather obvious - the order of usernames from the parsed file is not going to be the same order as in my database - due to people moving up and down the ranks. So i can't just get a recordset from the db and run a simple loop to compare it to the parsed data. I am not sure how to go about comparing the database information with the parsed data that works around the fact the data could be in any order. The only thing i can think of is: foreach item in $parsed_data_array query database for $parsed_data_array=>username if(number of results == 0) build new insert query for current username else continue I don't know if this works [haven't tested yet] but I can't help feel it is a little DB intensive. There could be up to 200 queries being sent to the database. This can be minimized by adding extra criteria, like ignoring inactive users of course. Is this a viable solution or is there a much better way of doing this?
