PHP - Php Code Is Not Searching The Correct Results.
i basically have a php search form on a property website, and depending on what area/type of property/number of bedrooms and price range the search form should bring up results based on that. at the moment it just bring up everything. how would i make it bring up the correct results depending on the search made?
here my php code: Code: [Select] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Mumtaz Properties</title> <link rel="stylesheet" href="cutouts/style.css"/> </head> <body> <!--Main Div Tag--> <div id="wrapper"> <div id="header"> <div id="logo"><a href="index.html"><img src="cutouts/Homepage/logo.png" alt=""/></a></div> </div> <div id="navigation"> <a id="Home" href="index.html" title="home"><span>home</span></a> <a id="Sale" href="forsale.html" title="for sale"><span>for sale</span></a> <a id="Rent" href="forrent.html" title="for rent"><span>for rent</span></a> <a id="Contact" href="contact.html" title="contact us"><span>contact us</span></a> </div> <div id="main"> <div id="results"><img src="cutouts/Homepage/results.png"></div> <?php $server = ""; // Enter your MYSQL server name/address between quotes $username = ""; // Your MYSQL username between quotes $password = ""; // Your MYSQL password between quotes $database = ""; // Your MYSQL database between quotes $con = mysql_connect($server, $username, $password); // Connect to the database if(!$con) { die('Could not connect: ' . mysql_error()); } // If connection failed, stop and display error mysql_select_db($database, $con); // Select database to use // Query database $result = mysql_query("SELECT * FROM Properties"); if (!$result) { echo "Error running query:<br>"; trigger_error(mysql_error()); } elseif(!mysql_num_rows($result)) { // no records found by query. echo "No records found"; } else { $i = 0; echo '<div style="font-family:helvetica; font-size:14px; padding-left:15px; padding-top:20px;">'; while($row = mysql_fetch_array($result)) { // Loop through results $i++; echo '<img class="image1" src="'. $row['images'] .'" />'; //image echo "<span style=\"color:#63be21;\">Displaying record $i<br>\n<br></span>"; echo "<b>Location:</b> ". $row['Location'] .

The page is at: www.giantstridedives.com/locations. You can see that it's pretty boring. Hit submit and you'll see the entries so far (only 3 right now). I'd like to have the latest 10 display there by default but then when a user searches they are replaced by the search results. Make sense? Here's the code I'm using for the search: Code: [Select] <?php if (isset($_POST['submit'])) { require_once('dbconnection.php'); mysqli_select_db($conn, $dbname); $searchterm = $_POST['search']; $searchterm = strip_tags($searchterm); $searchterm = trim ($searchterm); $q ="SELECT * FROM locations WHERE loc_name LIKE '%" . $searchterm .

Code: [Select] select * from table WHERE id > ((SELECT MAX(id) from table) - 10);I'm just not sure how I can display them by default and then have them be replaced by the search results. Anyone have any ideas for me? As always I appreciate the help as I continue to learn this beast. I am trying to implement lazy loading into a project with pagination already set up.
If I was to go to my website and after the .com, type in "api_courselist.php?page=1" I would receive the first 20 results of my query. If I was to change that to page=2, it would retrieve the next 20 and so on.
My issue is I have no idea how to implement that into my java script/ajax file. I have it set up so that when the user scrolls to the bottom of the page, a div will make its self visible with the new page populated inside of it and IT will keep on pulling pages in till There is no more content.
jQuery(function ($) {
jQuery(document).ready(function() {
var is_loaded = true;
jQuery(window).scroll(function() {
if(jQuery(window).scrollTop() == jQuery(document).height() - jQuery(window).height()) {
jQuery('div#loadMore').show();
if(is_loaded){
is_loaded = false;
jQuery.ajax({
url: "api_courselist.php?page=1",
success: function(html) {
is_loaded = true;
if(html){
jQuery("#infiscroll").append(html);
jQuery('div#loadMore').hide();
}else{
jQuery('div#loadMore').replaceWith("<center><h1 style='color:red'>End of Content !!!!!!!</h1></center>");
}
}
});
}
}
});
});
});

Thanks for your help very sorry if this is too basic Hi, The code for displaying a results set in multiple columns (http://www.phpfreaks.com/forums/index.php?topic=95426.0) works really well and displays 1 2 3 4 5 6 7 8 Does anyone know how to change so it displays as 1 3 5 7 2 4 6 8 Any help would be greatly appreciated thanks a i have an admin page that lists all the rows from a table. One of the fields is generated using FCKEditor, so the field has HTML Code in it. I would like to only show the first 100 or so chars of the field, but if the 100 chars ends in the middle of HTML code, specifically in this case <a href>, it cuts off, and creates "havoc" in my page. Is there a way to avoid this by seeing that the 100 char is in the middle of an <a href> tag (or any tag for that matter? Here is what the generated html can look like :: <td class="tdresults">We are very excited to offer three great events at the <a href="http://www.mylongwebsite.c</td> <td class="tdresults">next field data</td> Thank you in advance. Pete This topic has been moved to JavaScript Help. http://www.phpfreaks.com/forums/index.php?topic=355144.0 Hello all,
Based on the suggestion of you wonderful folks here, I went away for a few days (to learn about PDO and Prepared Statements) in order to replace the MySQLi commands in my code. That's gone pretty well thus far...with me having learnt and successfully replaced most of my "bad" code with elegant, SQL-Injection-proof code (or so I hope).
The one-and-only problem I'm having (for now at least) is that I'm having trouble understanding how to execute an UPDATE query within the resultset of a SELECT query (using PDO and prepared statements, of course).
Let me explain (my scenario), and since a picture speaks a thousand words I've also inlcuded a screenshot to show you guys my setup:
In my table I have two columns (which are essentially flags i.e. Y/N), one for "items alreay purchased" and the other for "items to be purchased later". The first flag, if/when set ON (Y) will highlight row(s) in red...and the second flag will highlight row(s) in blue (when set ON).
I initially had four buttons, two each for setting the flags/columns to "Y", and another two to reverse the columns/flags to "N". That was when I had my delete functionality as a separate operation on a separate tab/list item, and that was fine.
Now that I've realized I can include both operations (update and delete) on just the one tab, I've also figured it would be better to pare down those four buttons (into just two), and set them up as a toggle feature i.e. if the value is currently "Y" then the button will set it to "N", and vice versa.
So, looking at my attached picture, if a person selects (using the checkboxes) the first four rows and clicks the first button (labeled "Toggle selected items as Purchased/Not Purchased") then the following must happen:
1. The purchased_flag for rows # 2 and 4 must be switched OFF (set to N)...so they will no longer be highlighted in red.
2. The purchased_flag for row # 3 must be switched ON (set to Y)...so that row will now be highlighted in red.
3. Nothing must be done to rows # 1 and 5 since: a) row 5 was not selected/checked to begin with, and b) row # 1 has its purchase_later_flag set ON (to Y), so it must be skipped over.
Looking at my code below, I'm guessing (and here's where I need the help) that there's something wrong in the code within the section that says "/*** loop through the results/collection of checked items ***/". I've probably made it more complex than it should be, and that's due to the fact that I have no idea what I'm doing (or rather, how I should be doing it), and this has driven me insane for the last 2 days...which prompted me to "throw in the towel" and seek the help of you very helpful and intellegent folks. BTW, I am a newbie at this, so if I could be provided the exact code, that would be most wonderful, and much highly appreciated.
Thanks to you folks, I'm feeling real good (with a great sense of achievement) after having come here and got the great advice to learn PDO and prepared statements.
Just this one nasty little hurdle is stopping me from getting to "end-of-job" on my very first WebApp. BTW, sorry about the long post...this is the best/only way I could clearly explaing my situation.
Cheers guys!
