I start out by pulling a list of image urls from the database then I run it through a foreach loop to display the results and change the weight of the image

 

<?php foreach ($image as $image_arr){?>
<tr>
<td width="70"><center><img src="<?php echo $image_arr;?>" alt="rotation" /><br />
URL:<?php echo $image_arr;?></center>
<center>


<?php
//get image weights
$weightresult = mysql_query("SELECT weight FROM images WHERE url ='$image_arr'");
$weightrow = mysql_fetch_row($weightresult);
$weightcontents = $weightrow[0];

?>
higher weight images will show more often
<br />
<form action= "changeweight.php" method="post">
Weight (1 to 9): <input type="number" name="weight" min="1" max="9" value="<?php echo $weightcontents ?>" />
<input type="hidden" name="seturl" VALUE="<?php echo $image_arr ?>"/>
<input type="submit" VALUE="set weight" />
</form>

 

The problem is all the weight boxes work except for the first one. Could the fact that it is [0] in the array be messing it up?

 

Here is changeweight.php if it helps:

<?php
session_start();
//connect to db
include("dbc.php");


$setweight = $_POST['weight'];
$seturl = $_POST['seturl'];

mysql_query ("UPDATE images SET weight = '$setweight' WHERE url = '$seturl' ; ") or die (mysql_error());




header("Location: /xxxxxx/myaccount.php",TRUE,303);
?>

The problem is all the weight boxes work except for the first one

 

What exactly doesn't the first one do? Is it missing entirely from the form? Is the hidden field in the form incorrect? It doesn't update? It produces an error when the update query runs?

 

BTW - you should not execute one query, then loop over the result from that query and execute another query in the loop to just get data the first query should have already selected.

Thanks for the response. I'll try to explain a little better. The form displays properly in all of the foreach iterations. However the first iteration does not run changeweight.php when the submit button is clicked. All the other iterations work perfectly.

 

I added shuffle($image) before the loop and when the previous first iteration is no longer first , it updates weight fine.

 

Also, I understand what you mean about the query in the loop but not sure how to implement it outside the loop because I need the $image_arr variable from the foreach statement
