Can a link call a function somehow...?

madcat

Hi:

I built a function that prints text boxes on demand. If you press the link "Enter more numbers", 5 more boxes should be generated below existing text boxes...

Now, I'm trying to find a way to trigger that function so that it prints out the extra text boxes. Is there anyway to populate a control variable when that <a> is clicked on so that I can use it as a condition to print out the function when the link is pressed.

For example:

<?php 'the function' ?>

<?php (if test variable)-> function output' ?>

<a href="#" title="Enter More Numbers">Enter More Numbers</a> -> Populate a variable I can test...

See what I mean?

Hey there, nevermind...I figured it out.

I will populate a variable in the URL and use that to import a PHP include within the same file...

Or perhaps something like:

Here is what I'm trying to do:

index.php

num1
num2
num3
num4
num5

// print 5 more nums when link below is clicked...

if($_GET['genTexts'] == 1) {
include ('generateFields.php');
}

// link should call generateFields (below). The first time the link is clicked should bring up num6-num10. The second time should bring up num11-num15. I can't seem to work that out in generateFields.php either.

<a href="index.php?genTexts=1&what=Tracking&whatdb=track" title="Enter More Numbers">Enter More Numbers >></a>

generateFields.php <

<?php

if($i <= 10) {
for ($i=6; $i <= 10; $i++) {
$whatPlus = $GET['what'].$i;
$whatPlusdb = $GET['whatdb'].$i;
$newFields[$i] = "<tr><td>$whatPlus:</td><td><input type='text' size='25' name='$whatPlusdb' /></td></tr>";
echo $newFields[$i];
}
} else if($i >= 11) {
for ($i=11; $i <= 15; $i++) {
$whatPlus = $GET['what'].$i;
$whatPlusdb = $GET['whatdb'].$i;
$newFields[$i] = "<tr><td>$whatPlus:</td><td><input type='text' size='25' name='$whatPlusdb' /></td></tr>";
echo $newFields[$i];
}
}

Any help on this is greatly appreciated. Objective: The page shows five text fields. When the user has more than 5 numbers they should be able to click on the link to get another 5. Then, once more, another 5 for a total of 15 text fields.
