Pesky Checkbox Arrays And A MySQL Song Database
I'm not one who likes to ask for help, so for the last three days my brain has been turning to mush while I try to create a DJ Request Song Wish List. Anyone who can help me out will be saving me from severe insanity. :)
My goal is to:
1. Display search results for song title, artist and genre. (accomplished)
2. Allow the user to add songs to their Wish List. This is done by displaying checkboxes with the corresponding value equal to the songID. (working on it)
3. Allow the user to update their wishlist by adding/deleting songs.
So far I have a form that retrieves the song info from a database in a repeating region. In Dreamweaver:
<input name="songID[]" type="checkbox" id="songID[]" value="<b><?php echo $row_RecordsetSearchResults['Title'];?></b> by <?php echo $row_RecordsetSearchResults['Artist'];?>">
This puts the corresponding songID number into a checkbox value, which in turn is submitted by form POST action to the following page as an array.
To process this array I have:
if(isset($_POST['songID']))
{
$songID = $_POST['songID'];
print '<p>Song IDs:</p>'
// process items
$n = count($songID);
for($i = 0; $i <= $n; $i++)
{
//See if the values are being passed from POST
echo $songID[$i];
echo '<br>'
}
$songsInsert = '*'.implode('*',$_POST['songID']).'<br>'
$insertSQL = sprintf("INSERT INTO wishlist (Username, Title) VALUES (%s, %s)",
GetSQLValueString($MM_Username, "text"),
GetSQLValueString($songsInsert, "text"));
mysql_select_db($database_ToneDeaf, $ToneDeaf);
$Result1 = mysql_query($insertSQL, $ToneDeaf) or die(mysql_error());
}
The problem is, I'm using implode. It does store the songs, but only as one long block of text. So if the user picks "New York by Frank Sinatra" and "Hot In Here by Nelly" it is stored as "*New York by Frank Sinatra*Hot In Here by Nelly*" Obviously this gives me no options to make this actually readable, let alone allow the user to remove one of those songs from their list (both would be have to be removed.)
Also, referencing only the songID number as stored in the music database doesn't seem a good option, since the song database will be changing frequently and song data may be overwritten. Not sure if there's a viable workaround there.
Originally I wanted to store Title, Artist, Genre under seperate columns so I could link them to something like "See more songs from this Artist." However the more I read about arrays and multidimensional arrays, I realize I'm not ready to go there yet. (I just started learning PHP two weeks ago.)

How To Insert Arrays Into Mysql Database
This is my order.php file. Now I try to make a new php-file for processing the ordered items on this page, into another table "ordered_products" in the database. I want to INPUT following values into the table "ordered_products": 'order_num', 'order_item' and 'order_ant' I know how to insert rows in a table using the INSERT query, but I don't know how to do it while looping the arrays. I have to fetch the arrays from this page, and insert them row by row in the "ordered_products" table. Code:
Passing Checkbox Values Into The Correct Arrays
I've been looking at some code and the net for the past few hours trying to figure out what's wrong and I'm stumped. I have a form - multiple checkboxes (different names) and text fields going into an array. The text fields behave fine - the values from the first entry will populate elements of the first array. The weird part is that the check boxes will pass the correct values but not always to the correct array element. For example, given two check boxes in a 2 element array, if you check the 1st box in the first element and the 2nd in the second element, on submission, the second element populates the first array element. I've included a snippet of the code as an example - it's echoing things like crazy because I've been trying to see what's been going on. I hope someone can figure this out for me 'cause I'm completely stuck and am on a deadline. Code:
Problems Sending Arrays By Form When Type=checkbox
I have a problem when I try to send an array using a form when the type="checkbox". This is my form input row: <INPUT type="Checkbox" name="flg[]" value="y" <? if($row['flag'] == 'y') echo 'CHECKED' ?>> Since this is an update form, I set the status of the flg[] according to the field "flag" stored in a MySQL database. The user may check or uncheck each of the checkboxes on the form. This form is sent to another PHP file with other fileds of type <SELECT> and type="Text". Here's the code which process the checkbox input: $max_i = count($flg); for($i=0;$i<$max_i;$i++) { if($flg[$i] == 'y') { $flag = 'y' } else { $flag = 'n' } echo $i.'-->'.$flg[$i].'-->'.$flag.'<BR>' } I have no problems processing the array associated with the SELECT and "Text" fileds, but when I try using the Checkbox, this is what I receive: 0-->y-->y 1-->y-->y 2-->y-->y 3-->y-->y 4-->y-->y 5-->y-->y Trying with this other code: $num_of_checkbox_fileds = 12; for($i=0;$i<$num_of_checkbox_fileds;$i++) { if($flg[$i] == 'y') { $flag = 'y' } else { $flag = 'n' } echo $i.'-->'.$flg[$i].'-->'.$flag.'<BR>' } I receive this output: 0-->y-->y 1-->y-->y 2-->y-->y 3-->y-->y 4-->y-->y 5-->y-->y 6-->-->n 7-->-->n 8-->-->n 9-->-->n 10-->-->n 11-->-->n

What Goes Into The Database When You Submit Via A Checkbox?
I have a simple form with a checkbox and I thought that when the box is checked and I submit to the MySQL database then the number 1 would appear in the database and if it wasn't checked then a 0 would appear. But whether it is checked or not, a 0 appears. How do I make it so that a 1 appears if the box is checked?

Inserting Checkbox Data Into A Database
Typically, checkbox inputs have a name value of an array (something like <input name="options[]" type="checkbox" />). Is there an easy way for me to extract the values of such an array and insert them into the right database column? Or should I just bite the bullet and give each checkbox input a unique name so I save myself some confusion/readability?
Parsing Multiple Checkbox Variables Into A Database

Checkbox In Mysql Fields
PHP selects and shows a list of records. Next to each record is a check box.

Are there any tutorials or snips on how I'd do this?

Adding Checkbox Input To Mysql Db
how to pass a value from a form with a checkbox on a html page to a mysql database. I've preloaded some data and can populate a box if the data is already present in the db.

Passing A Checkbox Variable To A MySQL Db
Im the webmaster for a boxers website, and rather frequently, the publicist sends me links to articles about the boxer that I need to post. So, I set up a form that allows me to pull the information as needed and post it. Basically I have it set up to post the Article Title, Article URL, and Article Date, and I call that information from the db. However, on occassion, one of these links will be a press release, and the only thing that changes is that the text Press Release: is added in front of the article title. I was thinking about creating an extra field in the table called article_pr, and referencing that on the page, and if the row is empty, it would just pull up a space, and if its marked it just pulls up whatever is in there. However, on the form, I need to have a check box that asks if it is a press release. If so, I would need it to print this in the code Press Release:<br> Is there a way to have the check box indicate whether it will put that code in the db field?
Checkbox Values Stored In Mysql
I have a series of checkboxes and need to store their values in a MySQL table. I'm wondering what data type people recommend: varchar or text, exp. "True/False", "Yes/No" tinyint, exp. "0/1" Maybe it depends on the usage or maybe it doesn't matter and/or is a choice of personal preference.
Comparing PHP Array From Checkbox To MySQL Table
My problem involves updating a MySQL table using checkbox input. I'm relatively new to both PHP and MySQL so I'm looking for a little direction on the smartest way to accomplish my goal. When a user goes to a project page, they are able to categorize their project by area. The user checks a series of checkboxes and the results are stored in an arrays called $category_ids. I'll called the project id $project_id. What I want to do is compare the array $category_ids to entries in a MySQL table for $project_id. Then I want to add the links that aren't already in the table and delete the ones that need to be deleted. The table has these fields: projects_cat_link (table) ---------------------- category_id ¦ project_id (fields) Does anyone have any tips on how to do this? I've gathered that maybe there's a way to get the MySQL data into a similarly formed array and then use functions like array_diff to compare. But then I'm not sure how to use the comparison in a MySQL query to add/edit/delete the links.

What I'd like to do is the following: 1) Extract the data from the database 2) Separate each number it into an individual array value 3) Make the checkboxes in categories.php reflect the selected or non-selected state, based upon the results from the database (selected being the numbers in the database) Step 1 - I know how to do. Step 2 - I assume I need to use the explode function, no? Step 3 - Not a clue.... Code:

Passing PHP Arrays To Mysql Best Solution
I am relatively new to PHP and until now I have only needed to use relatively simple php/mysql solutions. I am working on a problem where I need to store CD information (Artist Name, Album Name, Track Names, Catalog Number) I am working on a solution with two tables "album" and "tracks" and I am using the catalog number as a key to link the two. The problem I am having is coming up with the best way to populate the tracks table as there are several tracks for each release. I am assuming that an array would be the correct way and maybe a dynamic form to input the tracks where you decide the number you need to add and this then creates a form with "n" input boxes?

I have a mysql database which I reach with php-code. I want to be able to download and open files I have stored(as a BLOB) in the database. Downloading and opening word documents and textfiles give no problems, but PDF-files aren't possible to open. Has anybody the same troubles, or does anybody know a solution for this problem?
Insert Into Mysql Database
It sounds very simple, but for some reason I just can't figure it out, and it will save a lots of time to me, if someone can direct me into the right direction. I was trying to input data into mysql table through post method, but it was not working. I made it simple and just tried to enter anything from a php file, but it does not work, so there is something that i am doing wrong with the insertion query. $link = mysql_connect($hostName, $userName, $password); echo("connected"); mysql_select_db($databaseName, $link); echo("database selected"); echo ($databaseName); mysql_query("INSERT INTO image VALES('','','','','','','','','', 'hello', '', '', '','','','','')", $link); echo ("done"); I am trying to enter into one of those fields, but it does not populate the table in mysql database.
