may I ask how can I add an autocomplete for my simple search engine.
Below is the Index.php
<html>
<head>
<title>Title of your search engine</title>
</head>
<body>
<form action='search.php' method='GET'>
<center>
<h1>My Search Engine</h1>
<input type='text' size='90' name='search'></br></br>
<input type='submit' name='submit' value='Search source code' ></br></br></br>
</center>
</form>
</body>
</html>
And here's the search.php
<?php

I don't really have idea how should i start it. Any help is greatly appreciated. Thanks!
I will give you the general shpill of how to do it. 1. Use ajax to fetch data. 2. present data. if you are using jQuery
$("#search").autocomplete(
{
source : function(request, response) {
$.ajax({
type : 'get',
url : "http://hostname.com/suggest.php",
data : {
search : document.getElementById("search").value
},
success : function(result) {
response(result.list);
},
dataType : 'json',
global : false
});
}
});
in your suggest.php
<?php
$str = $_GET['search'];
//query database, get results
echo json_encode(array('list'=>$mydata));
?>
and the id='search' to your search input tag

I have a search result with pagination that I make using this http://www.findsourcecode.com/php/pagination-in-search-engine/ as a reference. The website is using mysql and GET method for search. I change mysql to mysqli and work well. Then, I try to change the Get method to Post method for search result. The Post method is more secure based on what I readed. The question is how to change the method and make it work? The problem I face is, the result do not show at the second page but the first page show the result like I wanted. Please Helpp!!

Found a working code on PHP pagination here and i am trying to integrate this code into my search engine. I tried but the pagination function doesn't seem to work please can anybody tell me what's wrong with my code and any possible fixes.

The code above doesn't seem to work for some reason. I have tried to debug but cant't seem to find the error or errors. Any reasonable help would do with this. Thanks in advance.
First you set $start in your ternary logic:
$start = isset($_GET['start']) ? $_GET['start']: '';
After this, you check whether $start exists or not, and if it doesn't, you set it 0:
if (!$start) {
$start = 0;
$getQuery ...
while($row = $getQuery ...
The problem is all of your query and pagination logic is inside of this if conditional; if $GET['start'] is set, then your query and pagination logic will never trigger. And on top of this, all of your outputted <a> links do indeed send the start parameter:
<a href='pricearray.php?search=$search&submit=Search+source+code&start=$i'>
To resolve this, simply set your ternary to 0 for the failure condition, and omit the if conditional entirely:
$start = isset($_GET['start']) ? $_GET['start']: 0;
This can be seen in the following:
$start = isset($_GET['start']) ? $_GET['start']: 0;
$max_pages= ceil($countRet / $perpage);
$getQuery = $db->query("SELECT * FROM questions WHERE $condition LIMIT $start, $perpage");
while($row = $getQuery->fetchArray(SQLITE3_ASSOC))
{
echo '<tr><td>'.$row["question"].'</td></tr>';
}

Hi I have here a code which will search for a name then returns the result paginated. I'm having an error on lines 19 and 20 which is
Notice: Undefined index: submit in C:\xampp\htdocs\eventreg\trypaginate2.php on line 19 - NOW OK
and
Notice: Undefined index: search in C:\xampp\htdocs\eventreg\trypaginate2.php on line 20 - NOW OK
But it is working. When I turn to the next page it won't show any results just a blank page.
Here is my html code:
<html>
<head>
<title>Title of your search engine</title>
</head>
<body>
<form action='trypaginate2.php' method='POST'>

EDIT! Changed my php code now I'm getting an error on line 34. The error is Notice: Undefined variable: search in C:\xampp\htdocs\eventreg\trypaginate2.php on line 34
You shouldn't check whether a key exists in array (which is what $_POST and $_GET are) by blindly assigning variables to those values or even by using isset - even though I know that seems like it would make sense. That's the behavior that PHP is sending you a warning about. That error comes from trying to find the value of things like $_POST['search'] or $_GET['submit'] when those values aren't set in that array.
Instead, use array_key_exists('submit', $_GET) or array_key_exists('search', $_POST) to check whether those values are set. If that expression evaluates to true, then you can proceed with accessing those values in your code and you should not receive any notices in the logs.
i get undefined index: start at the line when i use $start = $_GET['start'];

Try this.

This is a search engine & pagination with one filter which is according to a word in "search", I want to add two more search filters: role & search between two dates.

You should rewrite you loop like this
//by name
$construct="true";
foreach($search_exploded as $search_each) {
$construct .= " AND name LIKE '%$search_each%'";
}
//by role
if($role) {
$construct .= " AND role = '$role'";
}
//by date
if($start) {
$construct .= " AND the_date >= '$start'";
}
if($end) {
$construct .= " AND the_date <= '$end'";
}
Otherwise you constantly reset the values of $x (which is not necessary anyway) and $construct.
Of course you would have to GET the dates/role and format them properly.
