Understood.
However, I have done this before using
$_POST['<--hardCodedValueGoesHere-->'] = NULL;. I was wondering if there
was a way to accomplish this with a loop structure instead of longhand,
line-by-line for each form value....particularly if I have a form with 30+
fields which I am required to build.
Currently this is the test form:
*****************************************************
<form name="dataPlayground" method="post" action="<?php
$_SERVER['PHP_SELF']; ?>">
<p>
<label for="textfield">First Name:</label>
<br>
<input name="firstName" type="text" class="inputCSS" value="<?php echo
$_POST['firstName']; ?>" id="firstName">
</p>
<p>
<label for="label">Middle Name:</label>
<br>
<input name="middleName" type="text" class="inputCSS" value="<?php echo
$_POST['middleName'] ?>" id="label">
</p>
<p>
<label for="label2">Last Name:</label>
<br>
<input name="lastName" type="text" class="inputCSS" value="<?php echo
$_POST['lastName'] ?>" id="label2"></p>
<p>
<label for="Submit"></label>
<input type="submit" name="mojo" value="Submit Me" id="Submit">
<label for="label3"></label>
<input type="reset" name="Submit2" value="Reset" id="label3">
</p>
</form>
*****************************************************
The reason I want to do what I want to do is two-fold:
1. Preserve entered data in the fields in case the form is not properly
filled out.
2. Use an array structure for error checking and changing the CSS
properties to visually indicate an error on the page.
--Like I said, I've done this before, I'm just looking for a short form way
to do it.
Thanks,
Rob
