onclick Event

[j-iN-uK]

Hi,

From a button_onclick, can I call a php script, if so please advise me, how I can do this.
<input type=button value="Search" onclick=SearchClick()>

function SearchClick()
{
$sql = "select * from table where Name like '%hello%'";
$result = mysql_query($sql);
if($row = mysql_num_rows($result)){
echo 'Number of results found '.$row.'.';
}else{
echo 'No results';
}
}

no that wont work...the php code will run before the page loads (before the button shows) so ..the php code and button will have to be on seperate pages

Yes the PHP code runs before the page but no you don't have to have the code in a seperate page.

Do I have to post the page to itself then!

You can not directly call a function in PHP via either a hyperlink or a form button. A similar question to this was just asked the other day and I've explained it here:

Yours would be done just slightly different when using a form button. You could use the $_POST array instead or still use the $_GET array whereas a hyperlink could only use the $_GET array. In your case you could check something like this:

<?php
function SearchClick(){
    //your search function code here
}

if(isset($_POST['search'])){
    SearchClick();
}
?>

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<input type="submit" name="search" value="Search">
</form>
