How To Generate and Process a Form with the Same Script
How To Generate and Process a Form with the Same Script? - PHP Script Tips - Processing Web Forms
✍: FYIcenter.com
In previous exercises, a Web form is generated by one script, and processed by another script. But you could write a single script to do both. You just need to remember to:
The PHP script below shows you a good example:
<?php if (!isset($_REQUEST['submit'])) { generatingForm(); } else { processingForm(); } function generatingForm() { print("<html><form action=submit_comments.php method=post>"); print("<input type=hidden name=module value=FAQ>\n"); print("<table><tr><td colspan=2>Please enter and submit your" ." comments about FYICenter.com:</td></tr>"); print("<tr><td>Your Name:</td>" ."<td><input type=text name=name></td></tr>\n"); print("<tr><td>Comments:</td>" ."<td><input type=text name=comment size=40>" ."</td></tr>\n"); print("<tr><td colspan=2>" .'<input type=submit name=submit value="Submit">' ."<td></tr></table>\n"); print("</form></html>\n"); } function processingForm() { print("<html><pre>"); $count = count($_REQUEST); print("Number of values: $count\n"); foreach ($_REQUEST as $key=>$value) { if (is_array($value)) { print(" $key is an array\n"); for ($i = 0; $i < count($value); $i++) { $sub_value = $value[$i]; if (get_magic_quotes_gpc()) { $sub_value = stripslashes($sub_value); } print(" ".$key."[".$i."] = ".$sub_value."\n"); } } else { if (get_magic_quotes_gpc()) { $value = stripslashes($value); } print(" $key = $value\n"); } } print("</pre></html>\n"); } ?>
If you save this script as submit_comments.php on your Web server, and submit this form, you will get something like this:
Number of values: 4 module = FAQ name = Ray comment = Good site for beginners. submit = Submit
