[Resolved] reading form input

TravisB

I have a form like this:

Image 1 Sort: File: Description:

Image 2 Sort: File: Description:

Image 3 Sort: File: Description:

...
Image 14 Sort: File: Description:

Image 15 Sort: File: Description:

For each image they can input the sort order, filename, and description all in text boxes. How can I echo this information after the user hits the submit button?

Assuming you use POST as your form method,

echo("
     For image one, you said: <br>
          sort=" . $_POST['image_one_sort'] . "<br>
          name=" . $_POST['image_one_name'] . "<br>
          etc etc
");

Do the field names have to be unique? Like image_1_sort, image_2_sort, etc. Or is there a better way to handle them maybe using arrays?

They need to be unique, although there's some tricks you can do if you name them with [] (like: "image_sort[]"). For safety and because of the needs of your app, I'd lean towards doing what you came up with: image_1_sort. With this, you can do something like:

for($a = 0; $a < count($numoffields); $a++)
  echo $_POST['image_' . $a . '_sort'] . '<br>';

And that would work just fine.

Ok, for the form I have code that creats a form like this:

<tr><TD class="main"><form ACTION="/admin/add_images.php" NAME="ADD_PRODUCT" METHOD="POST">
<table border="0" width="100%" cellspacing="0" cellpadding="0"><tr><td colspan="4">More Sleeping Sofa - Natural</td></tr>
<tr><td class="main">Image 1</td><td class="main">Sort: <input type="text" name="sort1" value="1"></td><td class="main">File: <input type="text" name="file1" value="01.004.jpg"></td><td class="main">Description: <input type="text" name="desc1" value=""></td></tr>
<tr><td class="main">Image 2</td><td class="main">Sort: <input type="text" name="sort2" value="2"></td><td class="main">File: <input type="text" name="file2" value="01.004-1.jpg"></td><td class="main">Description: <input type="text" name="desc2" value=""></td></tr>
<tr><td class="main">Image 3</td><td class="main">Sort: <input type="text" name="sort3" value="3"></td><td class="main">File: <input type="text" name="file3" value="01.004-2.jpg"></td><td class="main">Description: <input type="text" name="desc3" value=""></td></tr>
<tr><td class="main">Image 4</td><td class="main">Sort: <input type="text" name="sort4" value="4"></td><td class="main">File: <input type="text" name="file4" value="01.004-3.jpg"></td><td class="main">Description: <input type="text" name="desc4" value=""></td></tr>
<tr><td class="main">Image 5</td><td class="main">Sort: <input type="text" name="sort5" value="5"></td><td class="main">File: <input type="text" name="file5" value="01.004-4.jpg"></td><td class="main">Description: <input type="text" name="desc5" value=""></td></tr>
<tr><td class="main">Image 6</td><td class="main">Sort: <input type="text" name="sort6" value="6"></td><td class="main">File: <input type="text" name="file6" value="01.004-5.jpg"></td><td class="main">Description: <input type="text" name="desc6" value=""></td></tr>
<tr><td class="main">Image 7</td><td class="main">Sort: <input type="text" name="sort7" value="7"></td><td class="main">File: <input type="text" name="file7" value="01.117-6.jpg"></td><td class="main">Description: <input type="text" name="desc7" value=""></td></tr>
<tr><td class="main">Image 8</td><td class="main">Sort: <input type="text" name="sort8" value=""></td><td class="main">File: <input type="text" name="file8" value=""></td><td class="main">Description: <input type="text" name="desc8" value=""></td></tr>
<tr><td class="main">Image 9</td><td class="main">Sort: <input type="text" name="sort9" value=""></td><td class="main">File: <input type="text" name="file9" value=""></td><td class="main">Description: <input type="text" name="desc9" value=""></td></tr>
<tr><td class="main">Image 10</td><td class="main">Sort: <input type="text" name="sort10" value=""></td><td class="main">File: <input type="text" name="file10" value=""></td><td class="main">Description: <input type="text" name="desc10" value=""></td></tr>
<tr><td class="main">Image 11</td><td class="main">Sort: <input type="text" name="sort11" value=""></td><td class="main">File: <input type="text" name="file11" value=""></td><td class="main">Description: <input type="text" name="desc11" value=""></td></tr>
<tr><td class="main">Image 12</td><td class="main">Sort: <input type="text" name="sort12" value=""></td><td class="main">File: <input type="text" name="file12" value=""></td><td class="main">Description: <input type="text" name="desc12" value=""></td></tr>
<tr><td class="main">Image 13</td><td class="main">Sort: <input type="text" name="sort13" value=""></td><td class="main">File: <input type="text" name="file13" value=""></td><td class="main">Description: <input type="text" name="desc13" value=""></td></tr>
<tr><td class="main">Image 14</td><td class="main">Sort: <input type="text" name="sort14" value=""></td><td class="main">File: <input type="text" name="file14" value=""></td><td class="main">Description: <input type="text" name="desc14" value=""></td></tr>
<tr><td class="main">Image 15</td><td class="main">Sort: <input type="text" name="sort15" value=""></td><td class="main">File: <input type="text" name="file15" value=""></td><td class="main">Description: <input type="text" name="desc15" value=""></td></tr>
<input type="hidden" name="current_product_id" value="466"><tr><TD class="main" colspan="4"><input type="image" src="includes/languages/english/images/buttons/button_edit.gif"></td></table></form>
</td>
</tr>

Then I have this code to echo the submitted info:

<?php
$i = 1;
while($i <= 15){
	echo 'Image ' . $i . ': ';
	echo $_POST['$sort' . $i] . ' - ';
	echo $_POST['$file' . $i] . ' - ';
	echo $_POST['$desc' . $i] . '<br>';
	$i++;
}
?>

Which prints this:

Image 1: - - 
Image 2: - - 
Image 3: - - 
Image 4: - - 
Image 5: - - 
Image 6: - - 
Image 7: - - 
Image 8: - - 
Image 9: - - 
Image 10: - - 
Image 11: - - 
Image 12: - - 
Image 13: - - 
Image 14: - - 
Image 15: - -

Why I am not getting my information?

Weedpacket

Because you're asking for the values of $POST['$sort1'], $POST['$sort2'], etc., instead of $POST['sort1'], $POST['sort2'], etc.

Thanks. I kept staring at it but could not see what was wrong.
