AJAX and PHP LiveSearch

[slimboyfatz32]

Hi , I have recently touched on the AJAX/PHP LiveSearch tutorial on the W3Schools website , the problem i am up against is that my searches return a response to a letter (ie : D) that appears anywhere in the chosen search entry , not just the beginning (which is how i would like it , and more like googles auto-complete function) see for yourself http://www.atrium-improvements.co.uk/search.html the code for the PHP is here ....<?php$xmlDoc = new DOMDocument();$xmlDoc->load("links.xml");$x=$xmlDoc->getElementsByTagName('link');//get the q parameter from URL$q=$_GET["q"];//lookup all links from the xml file if length of q>0if (strlen($q) > 0){$hint="";for($i=0; $i<($x->length); $i++) { $y=$x->item($i)->getElementsByTagName('title'); $z=$x->item($i)->getElementsByTagName('url'); if ($y->item(0)->nodeType==1) { //find a link matching the search text if (stristr($y->item(0)->childNodes->item(0)->nodeValue,$q)) { if ($hint=="") { $hint="<a href='" . $z->item(0)->childNodes->item(0)->nodeValue . "' target='_self'>" . $y->item(0)->childNodes->item(0)->nodeValue . "</a>"; } else { $hint=$hint . "<br /><a href='" . $z->item(0)->childNodes->item(0)->nodeValue . "' target='_self'>" . $y->item(0)->childNodes->item(0)->nodeValue . "</a>"; } } } }}// Set output to "Business Type Not Found" if no hint were found// or to the correct valuesif ($hint == "") { $response="Business Type Not Found"; }else { $response=$hint; } //output the responseecho $response;?>

Instead of using stristr to do the check, use stripos and check if the return value is 0, that will mean that the substring starts the search string. http://www.php.net/manual/en/function.stripos.php

Find the if statement that has stristr in it. From the reference page for stristr apparently the first parameter is the haystack to search in, and the second parameter is the needle to search for:http://www.php.net/manual/en/function.stristr.phpFrom the stripos reference page it looks like it has the parameters in the same order, so you can just replace the function name with stripos and check if the return value is 0, there are examples on the stripos page to do that. You need to use the === operator instead of just == to make sure it is the number 0 and not boolean false.if (stripos($haystack, $needle) === 0)//haystack starts with needle

Good god. The links I gave you have all the information you need, but here's the version where you don't have to understand anything. Replace this line:if (stristr($y->item(0)->childNodes->item(0)->nodeValue,$q))with this:if (stripos($y->item(0)->childNodes->item(0)->nodeValue,$q) === 0)
