Recently I am writing a products catalog for my company. I use the dropdown list to provide a filter to a grid views product list that has pagination. The filter is work fine if products not more than 1 page. When more then one page of search result, the browser will show all products same as no filter applied. Below is my code of the index.php. Please help because I already stuck in here for a week. Thank in advance.

Your logic seems OK but your problem is when you navigate trough pages you make a new call of the document, which doesn't include variables like filters but the current page ($_GET['page']).
Either you send filters as variables trough URL as well, which isn't the cleanest way to do table pagination.
Or you gather results in a javascript array, and then on click on a pagination button display the previous/next rows. By doing this you also avoid refreshing the whole document every time, which isn't necessary.

Build SELECT query with dynamic number of LIKE conditions as a mysqli prepared statement

Closed 1 year ago.
I have created search engine so when someone type in search box it takes data from my database and show the results in images.
Everything is working fine but if I have data in database with Name like 'Lamborghini', when someone type in search box 'lambo' or 'Lamborghini' it is working fine and show the result but when he types 'Lamborghini car' it is not showing any result.
Here is my PHP Code:
<html>
<link href="css/imgpages.css" rel="stylesheet" type="text/css">
<head>
<title>Search the Database</title>
</head>
<body>
<form action="" method="post">
Search: <input type="text" name="term" /><br />
<input type="submit" name="submit" value="Submit" />
</form>
</body>
</html>
<?php
include("connection.php");
$term = $_POST['term'];
$query = mysql_query("select * from save_data where Title like '%$term%'");
while($row = mysql_fetch_array($query)) {
$post_id = $row['ID'];
$title = $row['Title'];
$image = $row['Name'];
?>
<div id="body">
<a href="pictures.php?title=<?php echo $title; ?>">
<div id="title"><?php echo $title; ?></div></a>
<a href="pictures.php?title=<?php echo $title; ?>">
<img src='uploads/<?php echo $image; ?>' width='140' height='140'></a>
</div>
<?php } ?>
You should:
fix your SQL (make it secure - just one search could delete your whole database if you leave it like this, switch to mysqli or PDO because mysql_* functions are deprecated)
split your query string into separate words and decide how to handle them (whether you'll use OR or AND... in other words, do all search terms need to match, or any of them, etc.)
When you deal with all that and decide to make it more advanced, you should learn about full-text searching.
It is 'cause { %$term% } means the query try search something that contain all of the string in $term. Try this :
$term = explode(" ",$term);
if (count($term) > 0) {
$Where = '';
foreach($term as $Item) {
$Where .= "Title like '%$Item%' OR ";
}
$Where = substr($Where,0,-4);
$query = mysql_query("SELECT * FROM `save_data` WHERE $Where");
}
In this way the search will check out all words.
As the above people said just Explode the input string into an array and search for documents(description, keywords) where most of the elements match. Also take care of SQL Injection.
first make your term search explode so it would go into an array
<?php
$term = $_POST['term'];
$words = explode(" ", $term);
?>
then create a forearch loop for the mysql_query of your search and implode with "OR"
<?php
foreach ($words as $words)
{
$queries[]="select * from save_data where Title LIKE '%" .
mysql_real_escape_string($words) . "%'";
}
$query=implode(' OR ' ,$queries);
$results=mysql_query($query);
while($row = mysql_fetch_array($results))
{
$post_id = $row['ID'];
$title = $row['Title'];
$image = $row['Name'];
?>
<div id="body">
<a href="pictures.php?title=<?php echo $title; ?>">
<div id="title"><?php echo $title; ?></div>
</a>
<a href="pictures.php?title=<?php echo $title; ?>">
<img src='uploads/<?php echo $image; ?>' width='140' height='140'>
</a>
</div>
<?php } ?>
I'm trying to sort a PHP generated form by price. I get an error message 'Notice: Undefined index: PriceDesc/Asc'. I understand the error message but can't find any relevant info through searching so thought I'd ask. I'm new to PHP and so far this is the code I have:

<?php

Print "<table border cellpadding=10>";
while($info = mysql_fetch_array( $data ))
{

}

For the record, I'm using PhpMyAdmin for my backend d/b and the initial tabled data works fine.
Replace
$data = mysql_query("SELECT * FROM products");
IF ($_GET['PriceAsc']){
$orderby =" ORDER BY price ASC";
}
IF ($_GET['PriceDesc']){
$orderby =" ORDER BY price DESC";
}
with
if ( !empty($_GET['sort']) && $_GET['sort'] == 'PriceAsc' ) {
$orderby=" ORDER BY price ASC";
}
if ( !empty($_GET['sort']) && $_GET['sort'] == 'PriceDesc' ) {
$orderby=" ORDER BY price DESC";
}
$data = mysql_query("SELECT * FROM products".$orderby);
Note the changes, you need to use empty() to check if form submitted and check the value of it. And do the query once Order by appended to SQL.
Yes append the $sort to the $data as above
and you'll need those query strings to be coming in correctly with the url
http://www/mypage.php?PriceAsc=true
and you'll need to compare it correctly
if ($_GET['PriceAsc']=='true'){
You never attached the $orderby variable to the query. Try this:
$data1 ="SELECT * FROM products";
IF ($_GET['PriceAsc']){
$data1 .=" ORDER BY price ASC";
}
IF ($_GET['PriceDesc']){
$data1 .=" ORDER BY price DESC";
$data = mysql_query($data1);
The .= appends the string to the end of $data
And reason you getting the undefined index error is because theres no PriceAsc available! Youre trying to $_GET something that doesnt exist.
What you need to do is :
IF ($_GET['sort'] == 'Price: Highest First'){
$data1 .=" ORDER BY price ASC";
} else {
$data1 .=" ORDER BY price DESC";
}
Need to make $courseInfo and $row global so that they can be used for printing the row details in the header DIV.
Don't have a clue how to do this. Any help would be great.
<?php
// Get Course ID From Link
$ID = mysql_real_escape_string($_REQUEST['ID']);
// Check the Course ID exists
$courseCheck = mysql_query("SELECT * FROM Courses WHERE CourseID = '".$ID."'");
if (mysql_num_rows($courseCheck) == 1) {
$checkMember = mysql_query("SELECT * FROM CourseMembers WHERE CourseID = '".$ID."' AND UserID = '".$_SESSION['UserID']."'");
if (mysql_num_rows($checkMember) == 1) {

I think they're already global. "PHP does not have a block-level scope."
You could store them in session variables, similarly to your $_SESSION['LoggedIn']
You could also use php variable $GLOBALS for making your variables visible in all scopes but I would not recommend it for this kind of task. Also, beware - $GLOBALS contains superglobals like $_POST and $_GET, you should keep that in mind, when ie. iterating over it. Furthermore - when you can access $_GET and $_POST in functions, that have smaller scope you still have to use $GLOBALS to access custom ones.
Example for this kind behaviour:
<?php
error_reporting(-1);
$GLOBALS['_customVar'] = 'foobar';
$GLOBALS['_GET']['id'] = 'myId';
function myFnc() {
echo $_customVar;
}
function myFnc2() {
echo $_GET['id'];
}
myFnc();
myFnc2();
?>
I wish to set the title of my webpage to Ultan.me - Whatever the post title. I want it to display the post title. The posts are submitted to a MySQL database and the title row is called "title". Any help is appreciated with this small question.
Update:
Here is the page itself now but it doesn't display the title. Should I open the php document and connect to my database somewhere different to it's current locations?
The Code (The only necessary piece is the beginning):

Here's the method I use (for similar things, not just title):
<?
ob_start (); // Buffer output
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<title><!--TITLE--></title>
</head>
<body>
<?
$pageTitle = 'Title of Page'; // Call this in your pages' files to define the page title
?>
</body>
</html>
<?
$pageContents = ob_get_contents (); // Get all the page's HTML into a string
ob_end_clean (); // Wipe the buffer
// Replace <!--TITLE--> with $pageTitle variable contents, and print the HTML
echo str_replace ('<!--TITLE-->', $pageTitle, $pageContents);
?>
PHP usually works be executing any bits of code and printing all output directly to the browser. If you say "echo 'Some text here.';", that string will get sent the browser and is emptied from memory.
What output buffering does is say "Print all output to a buffer. Hold onto it. Don't send ANYTHING to the browser until I tell you to."
So what this does is it buffers all your pages' HTML into the buffer, then at the very end, after the tag, it uses ob_get_contents () to get the contents of the buffer (which is usually all your page's HTML source code which would have been sent the browser already) and puts that into a string.
ob_end_clean () empties the buffer and frees some memory. We don't need the source code anymore because we just stored it in $pageContents.
Then, lastly, I do a simple find & replace on your page's source code ($pageContents) for any instances of '' and replace them to whatever the $pageTitle variable was set to. Of course, it will then replace <title><!--TITLE--></title> with Your Page's Title. After that, I echo the $pageContents, just like the browser would have.
It effectively holds onto output so you can manipulate it before sending it to the browser.
Hopefully my comments are clear enough.
Look up ob_start () in the php manual ( http://php.net/ob_start ) if you want to know exactly how that works (and you should) :)
You parse the field from the database as usual.
Then let's say you put it in a variable called $title, you just
<html>
<head>
<title>Ultan.me - <?php echo htmlspecialchars($title);?></title>
</head>
EDIT:
I see your problem. You have to set $title BEFORE using it. That is, you should query the database before <title>...
header.php has the title tag set to <title>%TITLE%</title>; the "%" are important since hardly anyone types %TITLE% so u can use that for str_replace() later. then, you use output buffer like so
<?php
ob_start();
include("header.php");
$buffer=ob_get_contents();
ob_end_clean();
$buffer=str_replace("%TITLE%","NEW TITLE",$buffer);
echo $buffer;
?>
For more reference, click PHP - how to change title of the page AFTER including header.php?
What about using something like:
<?php
$page_title = "Your page tile";
include("navigation.php"); // if required
echo("<title>$page_title</title>");
?>
Move the data retrieval at the top of the script, and after that use:
<title>Ultan.me - <?php echo htmlspecialchars($title, ENT_QUOTES, 'UTF-8'); ?></title>
You need to set the value of $title before echoing it.
Also, you should really sanitize any data before using it in queries as this is a security risk
create a new page php and add this code:
<?php
function ch_title($title){
$output = ob_get_contents();
if ( ob_get_length() > 0) { ob_end_clean(); }
$patterns = array("/<title>(.*?)<\/title>/");
$replacements = array("<title>$title</title>");
$output = preg_replace($patterns, $replacements,$output);
echo $output;
}
?>
in <head> add code: <?php require 'page.php' ?> and on each page you call the function ch_title('my title');
The problem is that $title is being referenced on line 5 before it's being assigned on line 58. Rearranging your code isn't easy, because the data is both retrieved and output at the same time. Just to test, how does something like this work?
Because you're only retrieving one row, you don't need to use a while loop, but I left it with hopes that it'll make it easier for you to relate to your current code. All I've done is removed the actual output from your data retrieval, and added variables for category and category name which are then referred to as usual later on. Also, I haven't tested this. :)
It'll be tricky to rearrange your code to make this work, but I'll try :)
So, put this at the top of your code:
<?php require_once('mysql.php'); ?>
The top of the file should look like:
<?php require_once('mysql.php'); ?>
<html>
<head>
<meta name="keywords" content="Mac user Ultan Casey TheCompuGeeks UltanKC">
<title>Ultan.me - <?php echo htmlspecialchars($title); ?> </title>
Then, create a file called mysql.php in the same directory that the file which contains the code you quoted is in.
Put this is mysql.php:
<?php
mysql_connect ('localhost', 'root', 'root');
mysql_select_db ('ultankc');
if (!isset($_GET['id']) || !is_numeric($_GET['id'])) {
die("Invalid ID specified.");
}
$id = (int)$_GET['id'];
$sql = "SELECT * FROM php_blog WHERE id='$id' LIMIT 1";
$result = mysql_query($sql) or print ("Can't select entry from table php_blog.<br />" . $sql . "<br />" . mysql_error());
$res = mysql_fetch_assoc($result);
$date = date("l F d Y", $res['timestamp']);
$title = $res['title'];
$entry = $res['entry'];
$get_categories = mysql_query("SELECT * FROM php_blog_categories WHERE `category_id` = $res['category']");
$category = mysql_fetch_array($get_categories);
?>
Well, hope that helped :)
I know this is an old post but having read this I think this solution is much simpler (though technically it solves the problem with Javascript not PHP).
<html>
<head>
<title>Ultan.me - Unset</title>
<script type="text/javascript">
function setTitle( text ) {
document.title = text;
}
</script>
<!-- other head info -->
</head>
<?php
// Make the call to the DB to get the title text. See OP post for example
$title_text = "Ultan.me - DB Title";
// Use body onload to set the title of the page
print "<body onload=\"setTitle( '$title_text' )\" >";
// Rest of your code here
print "<p>Either use php to print stuff</p>";
?>
<p>or just drop in and out of php</p>
<?php
// close the html page
print "</body></html>";
?>
Simply add $title variable before require function
<?php
$title = "Your title goes here";
require("header.php");
?>
header.php
<title><?php echo $title; ?></title>
<?php echo APP_TITLE?> - <?php echo $page_title;?>
this should work fine for you
if you want to current script filename as your title tag
include the function in your project
function setTitle($requestUri)
{
$explodeRequestUri = explode("/", $requestUri);
$currentFileName = end($explodeRequestUri);
$withoutExt = preg_replace('/\\.[^.\\s]{3,4}$/', '', $currentFileName);
$explodeCurrentFileName = explode("-", $withoutExt);
foreach ($explodeCurrentFileName as $curFileValue)
{
$fileArrayName[] = ucfirst($curFileValue);
}
echo implode(" ", $fileArrayName);
}
and in your html include the function script
and replace your title tag with this
<title>Your Project Name -
<?php setTitle($_SERVER['REQUEST_URI']); ?>
</title>
it works on php7 and above but i dont have any idea about php 5.*
Hope it helps
