POPHP Script to Ignore Placeholder Text in Input Fields
text
Body
copied!<p>I have the following script called <strong>form.php</strong>: <a href="http://pastebin.com/kHiZ3gLY" rel="nofollow">http://pastebin.com/kHiZ3gLY</a> (I have pasted full script below)</p> <p>When I complete the first set of 4 fields (leaving the other 2 sets with their placeholder text) and submit, my <strong>var_dump</strong> output is:</p> <pre><code>string '1|1|1|1 Height (cm)|Width (cm)|Length (cm)|Weight (kg) Height (cm)|Width (cm)|Length (cm)| ' (length=133) </code></pre> <p>Is it possible that I can use PHP/jQuery to "ignore" the fields that have the placeholder text in place? So my output would just be:</p> <pre><code>string '1|1|1|1' (length=7) </code></pre> <p>Many thanks for any helpers here.</p> <p><strong>full script:</strong></p> <pre><code><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" dir="ltr" lang="en-US"> <head profile="http://gmpg.org/xfn/11"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>March 2012 Experiment</title> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js" type="text/javascript"></script> <script src="http://digitalbush.com/files/jquery/watermarkinput/beta1/jquery.watermarkinput.js" type="text/javascript"></script> <script type="text/javascript"> jQuery(function($){ $("#p1height").Watermark("Height (cm)"); $("#p1width").Watermark("Width (cm)"); $("#p1length").Watermark("Length (cm)"); $("#p1weight").Watermark("Weight (kg)"); $("#p2height").Watermark("Height (cm)"); $("#p2width").Watermark("Width (cm)"); $("#p2length").Watermark("Length (cm)"); $("#p2weight").Watermark("Weight (kg)"); $("#p3height").Watermark("Height (cm)"); $("#p3width").Watermark("Width (cm)"); $("#p3length").Watermark("Length (cm)"); $("#p3weight").Watermark("Weight (kg)"); }); </script> </head> <body> <?php $errors = ''; if (isset($_POST['submitform'])) { $ierrors = array(); $all = ''; // Loop over the values 1 through 3 foreach( range( 1, 3) as $i) { // Create an array that stores all of the values for the current number $values = array( 'p' . $i .
