php function and form

**CreativeForce** · 02-16-2009 10:33 PM

hi i was wondering where in my script there's an error.
foobar.html

Code:

<html>
<head>
<title>
</title>
</head>
<body>
<form name="search" method="get" action="foobar.php?action=humbug">
Search</br>------</br>
<label for="title_search">Title</label></br>
<input id="title_search" name="title_search" type="text"></br></br>
<input type="submit" value="Search!">
</form>
</body>
</html>

foobar.php

Code:

<?php
function humbug(){
mysql_connect("","","") or die(mysql_error());
mysql_select_db("") or die(mysql_error());
$title_search=$_GET["title_search"];
$result=mysql_query("SELECT * FROM ml WHERE title LIKE '%$title_search%'");
while($rowresult=mysql_fetch_array($result)){
echo "<tr><td class='title'>"; 
echo $rowresult['title'];
echo "</td><td class='year'>"; 
echo $rowresult['year'];
echo "</td><td class='view'>"; 
echo $rowresult['1st'];}}
?>

if i make the action to foobar.php AND write the php script not as a function it works. what am i doing wrong?

Are you calling the function in your file?

A function only gets processed when it is called. Simply calling a script that has a function definition in it will not fire off that function. (For that matter, if that is all the "foobar.php" script does, then there is no real reason to put it into a function.)

If you have a reason to put the functionality in a function, then you would have to do something like:

PHP Code:


<?php
function humbug()
{
   // blah blah blah . . .
}

// invoke it:
humbug();
?>

foobar.php is a file with many php functions.

when i submit the form in foobar.html. i want to run a specific function known as function humbug() in foobar.php.

how do i do that?
