Check If A Table Has A Column Or Not?
I've got a training center for a bunch of different animals, but these animals don't have the same stats. So, basically, I want all of the animals to be available to train, and if they try to train an animal, I need code that checks if there is a certain column in a table, or if that animal has a specific stat. How would I do this?
Check For Existing Username
I have a MySQL database that uses create new accounts via HTML form. I need PHP to check to see if the username of the new account already exists in the user database, if so, report a message "Username already exists, please pick another one" (for example). If the username doesn't exist, then continue adding the new user account information to the database. Below is the PHP code that is run when the form information is submitted. PHP Code:
Table And PHP Scripts For Existing Data
I've been using MySQL for several months and enjoyed great success when installing other people's scripts to databses I make using phpMyAdmin. My challenge is developing from scratch the scripts, for which I've got good resources, manuals, and much time into practice and test. My question is three-fold, as I have 14,000 records of Security Dealers that I want to install in MySQL at www.securitydealers.com 1) what should my table SQL statement look like for data (sample) as follows; "John Doe","Managing Partner","BM SECURITIES LTD.","P.O. Box 201","Grand Cayman","Cayman Islands,"","","345--555-5999", 2) once the table is created inside my database on MySQL, how do I load the data in? 3) what is the best choice of variables, operators and arrays for my PHP script, to display only records from a certain city, country, company name or Dealer name?
Checking For Existing Data In Mysql Table..
I'm having a bit of a problem on a project I'm working on.. Here's the deal: I want to log search terms. Easy enough, right? Well, to make things interesting, I want to *NOT* log terms less than 3 chars long, *AND* if the term's already in the database, I don't want to add the term again, I just want to update the 'count' field to reflect that there was a 'hit' to the word. Here's how I coded it note: it doesn't work because I suck and I have no real idea how to do what I'm trying to do): This is the actual "recording" code I came up with: if(strlen($term)>3){ $record_term = sql_query("insert into $terms(ID, Term, count) values ('', '$term','')"); Now, this is the code I've come up for for the adding to the count part.. (and I know it's wrong, if someone can fix that too, I'd appreciate it): $query = mysql_query("SELECT term, count FROM Term WHERE term like $term;"); $entry = @mysql_fetch_array($query); $new_count = $entry["count"]+1; $query = mysql_query("UPDATE links SET count = $new_count, WHERE Term like $term;"); mysql_close($db); ----------------------------------------- So how do I combine these two actions to do what I want it to do? and what's wrong with the second query?
Check If Column In Mysql Exists With Php
I wanted to know if you can let php check if a column exists in a table. cuz i have a 1 script script and i want it to check a table for having the following columns and if 1 o fthem is missing it would automaticly add the column.
Column Table
I have a table of records; the records belong to different user ids and are distinguishable by a reference number, Each record has a price. so theres a price column. The problem isnt getting the total of the whole column. the problem is getting the total for the specific user id and displaying it at the bottom of the price column.
Column Data From One Table To Another
im trying to get the vend_name column data from one table(manuf) into another table (products2) that has the same vend_name column which is empty but has a vend_code column as a key identifier. im wondering if theres a way to put the data from the vend_code column and vend_name column from the first into an array so that i can populate the vend_name column of the 2nd table this is what ive come up with below, it seems to be just puting the last record into those two array variables PHP Code:
Building Table By Column Rather Than By Row
I'm currently looking for a way to populate some html tables of varying lenghts and widths, pulling the data from arrays. I want to achieve this with a function in order to make this as dynamic as possible. example: function build_table($data){ ... } $data would be an array containing a varying number of sub-arrays, the first array would populate the first row (column headings) and each subsequent array would be the data for each column rather than each row. Code:
Create A One Column Table
Using the following code, how do I create a one column table, with "Firstname, Lastname & Sex" as the heading. Also, how do I display the row data (i.e Firstname etc) using the following format?: Code:
Displaying Information In A 1 Row/2 Column Table
I'm very new to php scripting and haven't quite figured out what I need to do here. I need to display information in a 1 row/2 column table. I have the MySQL query working fine, but the scripting part in php is killing me! In the first column a graphic about 70x70 will be shown (plus some additional padding). In the second column will be the description information. The second column will be around 400 pixels wide. How do I set this up in php? It's easy enough in HTML, but I've about killed myself trying to figure out how to properly lay this out in php!
SELECT * FROM Table WHERE Column IS NOT NULL
I am running the following MySQL query: <?php $sql = mysql_query("SELECT * FROM comics WHERE story_arc IS NOT NULL") or die (mysql_error()); while($row = mysql_fetch_assoc($sql)) { echo $row['title']; } ?> The problem is that it is outputting all 4000+ records, when it should only be about 100. Is there an error with my 'IS NOT NULL'?
Search Only Works With Table Column Name
I have tried several different codes to create a database search of a table that includes column name "Product," "Price" and "InStock." I am trying to search the "Product column and in each code when I enter a term I know to be in the table it comes up with an error (usually "Unknown Column 'input' in 'where' or mysql_fetch_array(): supplied argument is not a valid MySQL result resource in"). The only way the search works is if I enter the actual name of the Column (in this case "Product") and it displays the entire table.
Recursive Array From A Twin-column Table
I have a MySQL table with two columns: catagory and parent. Parent contains the parent catagory of the catagory. I need to query the db ONCE, assigning the info to an array, then create a recursive array parenting catagories and grouping accordingly.
Displaying SQL Query Results In 3 Column Table
I would like to be able to display the results of an sql query in an html table, but the results need to be displayed in three columns, for example: Column 1 Column 2 Column 3 Result 1 Result 2 Result 3 Result 4 Result 5 Result 6 Result 7 Result 8 Result 9 I've tried to find the answers on the internet but i can't find anything that suits my needs!
Valid MySQL Database/table/column Name Regexp
regular expression in PHP which could be used to check that a proposed (My)SQL database/table/column name is valid, i.e. shouldn't result in an SQL error when created? The user of my (hopefully to be opensourced) program has the ability to create database/table/column names on the fly. I'm aware of obvious characters such as ., [space], things like >, etc., which won't work, but haven't been able to source a definitive list, including having googled the MySQL site. Obviously certain characters need to be filtered out, as noted above, but I want to be as unrestrictive as possible; hence just [a-z]* isn't good enough because things like _ are acceptable. Ideally, I'd prefer a regexp that applies to _all_ vendors' databases, not just MySQL as I'm about to migrate the program to being database-independent, probably using PEAR DB, but even a MySQL-specific regexp would do the job. In the longer term, I plan some sort of entity conversion script so that theoretically any character could be used, using some sort of escaping mechanism probably.
Select From Drop List To Fill Table Column With Text -- HOW ?
I want viewers to compare state laws on a single subject. Imagine a three-column table with a drop-down box on the top. A viewer selects a state from the list, and that state's text fills the column below. The viewer can select states from the drop down lists above the other two columns as well. If the viewer selects only one, only one column fills. If the viewer selects two states, two columns fill. Etc. I could, if appropriate, have a separate htm page with the text for each state -- california.htm for example. When the viewer selects California from the drop down list, the column below would "fill" with California.htm. Or, I could conceivably use a text or mysql database with two fields for each record: state_name and law_text -- but it would probably be easier to use separate htm files, since there will only be about 20 states involved, and the "database" would never have a large number of records. The table width would be 100% and each cell would be @33% My site is designed with FP 2002 and runs on Apache/FreeBSD. I have just had Apache-ASP installed but I have not yet configured or used the module.
Display Database Output In Mutli Column Html Table
I am building an HTML form using data from a mysql query. The data to be displayed on the form is 1 column from the db - but multiple rows. Because there are many rows (well, only about 100+) in the table I want to be able to put 2 or 3 (space permitting) rows from the result on each row of the HTML table with a checkbox beside each entry from the db table. The idea is that the user will scroll down the list and check up to 4 or 5 boxes before submitting the form and I didn't want them to have to scroll ALLLL the way to the bottom (100+ rows). I understand how to get data from a db table and put it into an html table, but I cannot figur out how to put more than 1 row from the result on to the same row of the html table. I hope I haven't confused anyone reading this -- If I am way off base with what I am trying to do please give me alternatives. I am trying to avoid paginating the data for a couple reasons a) clicking a next and/or prev button is more hassle than just scolling down a list and b) the data in the column being displayed is only about 35 - 40 characters and it seems to be if i only placed one result row on each html table row, there would be a lot of wasted space.
How To Check And Update Table?
I am trying to work out the best way to update the details in a table I have for customer data. Each time the customer interacts with the script all the data that is used in the table is sent to the script from an external source. What I want to do is check to see if the email address is already in the table. If it is I want to check all the other fields and update the data. If the email address is not in the table I want to add all the details as a new user. I am playing with this code but I can't see to get check right to see if the email address exsists. This code always inserts a new customer into the table.
Check Contents Of Mysql Table
ok, so now that I've figured out how to allow users to upload files (with help!) I'm trying to run a script that will check the name of the uploaded file and determine if that file name already exists in a specific mysql table. Here's what I've got so far: $filename = $_FILES['uploadfile']['name']; $query = "SELECT * FROM $table"; $result = mysql_query($query, $conn); while ($checkfile = mysql_fetch_assoc($results)){ $existfile = $checkfile['filename']; }//end while if ($existfile == $filename){ print "A file with that name already exists."; } else { some script that adds the file info to $table } Now, this combination of while and if statements will only catch a match with an already existing filename if the already existing filename was the last one to be updated. I've tried adding the if and else statements into the while statement but then the file info gets added to the table multiple times. Does anyone have any ideas? Am I even making any sense?
Check If Any Items In An Array (php) Is In A Table (mysql).
I want to check if any of the items in a PHP array exist in a MySQL table. What is the best way to do this with making repeated calls to the database for each item? Actual application is: I have an array (in PHP) of serial numbers of units about to be shipped.I want to check the ship record (a table in a MySQL database) to check if that serial number has been used before. According to our quality policy we never reuse serial numbers, serial numbers are unique. So prior to printing the packing slip I want to warn the shipping guy/gal a serial number may be incorrect. I could brute force it and increment through the "to be shipped array" and check each item against the table. But that is, as I said brute force, and I am having to be concerned with system speed lately.
How To Query From One Column Then Sort Using Another Column
I am trying to get the last 100 albums I entered into my database using the album_id (Highest being the latest entry) then sort them alphabetically using the album_title column. I can get the latest 100 easily but cannot figure out how to also sort the results by the album_title before I display them. This is what I have so far which gets what I want but not in alphabetical order. <?php $sqlquery = mysql_query("SELECT * FROM albums ORDER BY album_id desc limit 100", $db); while ($result = mysql_fetch_row($sqlquery)) { echo "<a href='music_info.php?album_id=$result[0]'><span style='text-decoration: none'>$result[1]</span><br></a>"; } ?> I have been trying to add a second ORDER BY to the query like so. $sqlquery = mysql_query("SELECT * FROM albums ORDER BY album_id desc limit 100 ORDER BY album_title", $db); but this obviously isn't the way I should be doing it.
Existing File Name
I am retrieving a fielname for a picture in PHP/MySQL and would like the existing filename that is being retrieved from the database to be shown in a file input. How do I do this please? If I simply use a value statement nothing is shown even though I know the variable holds the correct value. The code I am using is $picture1filename = $myrow[4] ; echo " myrow[4] in form " . $myrow[4] . "<br>"; echo " picture1filename in form " . $picture1filename ; echo ("<td colspan=ƈ'><input name='picture1' type= 'file' size=ྌ' value= '$picture1filename'>"); The echos are just there to show that the correct value has been found.
Embedding Existing Application
How do you embed an existing application as a module in a CMS (i.e. phpNuke, Xoops.) Let's say I want to modularize phpMyAdmin in phpNuke, is there a simple way to do this? I can design application so that it can be deployed as a module but how about for an existing app? Is this where WSRP comes in?
Dumping All Existing Variables
Does anybody know a way to dump all used variables and their content? Is that at all possible? I am looking for something like print_r(), but have no clue what to feed the function. I am mainly interested in variabled created in the script itself, not $_SERVER and the like. (I need this for debugging, and get tired of echoing all I might be interested in.)
Checking For Existing Files
If I include a file using include() or require(), is there a method of checking for the existance of the file before including it, therefore skipping the dreaded error message; or alternatively, supressing the error completely?
MySQL Existing Connection?
is there a way to check with PHP whether a mySQL connection already exist between a script and the database. In that case it can be decided to connect or leave things as is.
Parsing Existing PDF Documents
I have an existing PDF document; "myfile.pdf". I want to be able to seek through that document for particular strings. The thing is, I can't find a way to open the file as something that's legible/readable. I've tried using PDFLib aswell as using fopen/fgets (among many other things) to open the file and display the content. The only content I get is a little mark-up and a bunch of garbbled text. I'm assuming that when a PDF is created it has some form of character encoding passed over it, or it's encrypted in some way. I've looked at a few classes around, but none show ways of opening a PDF document up.
Call Non-existing Function...
what I basically want to do is to first check if the function hei() is available, if it is I want to call it, and if it's not the script should just skip it and continue to the next thing. I'll try to sketch the whole thing.... (It's from PHPNuke, which many of you might know) header.php <- in this file I want the script, it contains the top of the page. currently if I just insert a <?php hei(); ?> it will call the function if it is available, but report an error and not proceed if it isn't. index.php <- static page, containing the hei() function, also with an include("header.php"). none.php <- static page, NOT containing the hei() function, this is where the error occurs...

Integrating A CMS With An Existing Design
I'm after suggestions for a CMS to use with an existing design. Here's what the site looks like: Pulse I guess CMS is probably a little too grand for what I want. I just want to be able to update the text on each of my pages without editing the design. I've implemented solutions like TinyMCE before and think it's an ideal editor to use, but I need to be able to integrate this with something that can handle the content.
Installing GD On Existing PHP Installation
I want to install GD on an existing PHP installation without reinstalling php. Is this possible? If so how? I already did the following (fedora) yum install gd-devel Which went well I restarted my webserver (apache), but when I type php -m the gd module is still not listed. What else do I need to do?
Changing Existing Image

I need the user to change the existing image so that the new link is updated or replaced in the XML file.
Editing Colours In Existing Image- How?.
I'm having a little trouble finding out how to edit the colours of an existing image and output it through php. For example, if I tell it to read an image in a folder but change X colour, how would that be done? The only ways I've discovered so far involve images made there and then, on-the-fly, not existing files.
Automatically Add Unique Id To Existing Mysql Db
I am working on a MySQL db (+/- 18000 items) which was converted from FoxPro. But is doesn't have a unique id-field and I was wondering how to add such a field and the incremented numbers in it automatically, without having to enter 18000 unique numbers.
TLS Stream Wrapper On Existing Socket
I implement a proprietary protocol, which consists of cleartext messages (much like FTP) and has a TLS mode, which will be initiated by a "AUTH TLS" command (also, like for FTP). After send AUTH TLS, the whole TLS negotiation starts and the following communication will be wrapped in TLS. Instead of implementing TLS by myself, I would like to use the stream wrappers. But how? Something like fopen("tls://...") does not help me here. A stream filter for tls (instead of a wrapper) would be perfect for this purpose, but it does not exist. Or something like freopen().
Writing To Existing Text File
I am having some problems writing to a file that already exisits. I can create a new file and write to it, but when I try to write to that file later it fails. When a form is submitted the text from that form is to be written to a file. The user is then redirected to a page advising of the outcome of the submit. IE Success, data written, Failure (The file could not be opened) or Failure (The file could be opened, but not saved). Code:

Adding To Existing Uneditable Site
I want to use php to allows those visiting my site to browse realtor.com, but add some things to the pages it returns. For instance, if i detect that a user has come across a certain house, i want to add a link to another site, and make it look like it was a part of the realtor.com page. I also might want to add some css so that whenever a page being visited meets certain criteria, I display certain css to highlight an area of the page. Is this possible? How do I do it? What terms do I need to search for examples?
Integrate Captcha Into Existing Script
can anyone show an example that incorporates a captcha security code element into an existing script/form that queries a database? Of the many captcha scripts that have "demos" I can't get any of them to work within any of my existing search scripts...The captcha scripts work but only as a gateway to the search scripts (different page or frame etc)... ...How can I get the query search to only execute if/when the correct security code is entered...by clicking a single "submit/search" button ...that executes both the captcha and the query scripts?
