Strange include() behaviour

jstam

When I include another php file with a form, spaces get added in the source.

Here is the pertinent code.

From the first file:

include('../feedbackform.php');

feedbackform.php:

<?php
$module_id = $_POST['module_id'];
?>
<input type='hidden' name='module_id' value= '<?php echo $module_id;?>'>

What the source code says:

Where did the space before 4 ($module_id) come from??

Thanks!

Did you re-type the source, or did you copy and paste?

jstam

I copy pasted the source. The space before the 4 is what I was referring to

laserlight

the space should be before the single quote before the 4.

Test with:

<?php
$module_id = $_POST['module_id'];
?>
<input type='hidden' name='module_id' value='<?php echo $module_id; ?>'>

jstam

That worked, thanks!

But... Could you please tell me why my original code printed that space?

I have no idea.

The clientside source code should have been:

<input type='hidden' name='module_id' value= '4'>

not

<input type='hidden' name='module_id' value=' 4'>

but for some reason it was the latter.

Your serverside source code had a space after the =, so naturally it should be reflected in the clientside source code.
That an included file was involved didnt matter.
