PHP - Adding Limit To Code?
I had a piece of code which limited the number of items printed from a database. However, I can no longer get it to work.
Code: [Select] $query = "SELECT * FROM productfeed WHERE description like '%$description%' LIMIT 0, 3"; This is the code I am trying to limit, but I cant get it to work. Code: [Select] <?php ini_set('display_errors', 1); error_reporting(-1); $query = "SELECT * FROM productfeed"; if(isset($_GET['description']) && !empty($_GET['description'] )) { $description = $_GET['description']; $query .= " WHERE description like '%$description%'"; } if(isset($_GET['price']) && !empty($_GET['price'])) { $price = explode('-', $_GET['price']); $lowPrice = (int)$price[0]; $highPrice = (int)$price[1]; $query .= " AND price BETWEEN $lowPrice AND $highPrice"; } $result = mysql_query($query); while($row = mysql_fetch_assoc($result)) { $id = $row['id']; $image = $row['awImage']; $link = $row['link']; $description = $row['description']; $fulldescription = $row['fulldescription']; $price = $row['price']; echo "<div class='productdisplayshell'> <div class='productdisplayoutline'> <div class='productborder'><center> <a href='$link' target='_blank'><img src='$image' width=\"95%\" /></a> </center> </div></div> <div class='productdescriptionoutline'> <div class='productdescriptionbox'> <a href='$link' target='_blank' >$description</a> </div> <div class='productfulldescriptionbox'>$fulldescription</div> </div> <div class='productpriceoutline'> <div class='productpricebox'> <center>&#163; $price</center> </div> <div class='productbuybutton'> <center><a href='$link' target='_blank' ><img src=/images/buybutton.png /></a></center> </div> </div> </div>"; } if ($_GET['description'] == $description ) { echo 'Sorry, this product is not available. Please visit our <a href="http://www.ukhomefurniture.co.uk">Homepage</a>.'; } ?> <?php function sanitizeString($description) { $description = mysql_real_escape_string($description); $description = stripslashes($description); $description = htmlentities($description); return $var; $price = mysql_real_escape_string($price); $price = stripslashes($price); $price = htmlentities($price); return $var; } ?> Similar TutorialsI'm trying to add a file size limit to my upload form-code (below) I want to limit this tag to 25 characters when file runs, now it can be anywhere from 7-40 characters $teams = explode(" v ",$hie->Name);

There is also one called 'localhost/admin?limit=all' that is to show all the rows in one page.

I am trying to figure out the proper PHP method for setting a boundary on a variable within a script. I have this variable $name which is fed a value from $_POST['name'] from a form field. Now this form field is limited in the HTML to accept only 20 characters, but someone could easily edit the form or outgoing post data. So I want to know how to limit the variable size in the script. In other languages it could be something like this: var name(20). So how do I do that in PHP? Hi, I have some code which displays my blog post in a foreach loop, and I want to add some social sharing code(FB like button, share on Twitter etc.), but the problem is the way I have my code now, creates 3 instances of the sharing buttons, but if you like one post, all three are liked and any thing you do affects all of the blog post. How can I fix this? <?php include ("includes/includes.php"); $blogPosts = GetBlogPosts(); foreach ($blogPosts as $post) { echo "<div class='post'>"; echo "<h2>" . $post->title . "</h2>"; echo "<p class='postnote'>" . $post->post . "</p"; echo "<span class='footer'>Posted By: " . $post->author . "</span>"; echo "<span class='footer'>Posted On: " . $post->datePosted .

Ive tried adding my code in as standard PHP and also tried it with the {php}.....{/php} tags but it still doesnt work. Any help appreciated! Thanks Tom Hi, I am using Mouseflow analytics in a phpbb forum. In my specific application, I need to add their application's javascript code inside php code. How do I properly add Javascript code inside a php code. Thanks This is how I would add it to an html file <script type="text/javascript"> var _mfq = _mfq || []; (function () { var mf = document.createElement("script"); mf.type = "text/javascript"; mf.async = true; mf.src = "//cdn.mouseflow.com/projects/b22343cd9-0049-4443-8326-954444462d6515.js"; document.getElementsByTagName("head")[0].appendChild(mf); })(); </script> This topic has been moved to PHP Applications. http://www.phpfreaks.com/forums/index.php?topic=354302.0 Hello, Below is my existing code for my web site visitor to fill out the form... they see a thank you html page.... and I get the info inserted into my database.... and I get an e-mail with all their details, even their date of registration. From what I have seen so far, EVERYTHING WORKS SUCCESSFULLY. HOWEVER, I would like to have the web site visitors details that they filled out ALSO SENT BACK to the web site visitor as a confirmation... say that this is a confirmation of the form they previously filled out. How do I accomplish this based off of my existing code here? I also would like my thank you.html code at the bottom of my current php code to be called in from a SEPARATE REDIRECT thankyou.php page after a successful form entry. I know that ALL headers must be IMMEDIATELY taken cared of upon entering any php page. This is what i used ***** header("Location: thankyou.php");******* Now I know that this is the correct code to make this happen but i do not know how to get this to work with my present code here. How do put the header location: thank you.php code in my EXISTING PHP page to make this all work right? thanks mrjap1 Code: [Select] ====================== HTML ========================== <?php require_once("db_connection.php");?> <!DOCTYPE HTML> <html lang="en"> <head> <meta charset="UTF-8"> <title>HTML form for insert users</title> <style type="text/css"> p { margin:0; padding:0; font-family:Arial, Helvetica, sans-serif; font-size:12px; color:#633; font-weight:bold; } legend { font-family:Arial, Helvetica, sans-serif; font-size:15px; color:#3F6; font-weight:bold; } #form_container { background:#F7F; margin: 50px auto 50px auto; border: 1px solid #F00; padding:10px; width:285px; height:150px; } input { margin-bottom:5px; } body { background-color: #033; } </style> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> </head> <body> <?php if (isset($_POST['submit'])) { // Handle the form. $message = NULL; // Create an empty new variable. // Check for a first name. if (empty($_POST['first_name'])) { $first_name = FALSE; $message .= '<p>You forgot to enter your first name... its Required!</p>'; } else { $first_name = ($_POST['first_name']); } // Check for a last name. if (empty($_POST['last_name'])) { $last_name = FALSE; $message .= '<p>You forgot to enter your last name... its Required!</p>'; } else { $last_name = ($_POST['last_name']); } // Check for an email address. if (empty($_POST['email'])) { $email = FALSE; $message .= '<p>You forgot to enter your email address... its Required!</p>'; } else { $email = ($_POST['email']); } } ?> <div id="form_container"> <form action="form_proceessed201XXX.php" method="post"> <input type="hidden" name="submit" value="true" /> <fieldset> <legend>My Data Feilds</legend> <!-- ### FIRST NAME ### --> <p> <label>First Name:</label><input name="first_name" type="text" value="<?php if(isset($_POST['first_name'])) echo $_POST['first_name']; ?>" id="first_name" size="15" maxlength="30"> </p> <!-- ### LAST NAME ### --> <p> <label>Last Name:</label><input name="last_name" type="text" value="<?php if(isset($_POST['last_name'])) echo $_POST['last_name']; ?>" id="last_name" size="15" maxlength="30"> </p> <!-- ### EMAIL ### --> <p> <label>E-mail:</label><input name="email" type="text" value="<?php if(isset($_POST['email'])) echo $_POST['email']; ?>" id="email" size="15" maxlength="30"> </p> <!-- ### SUBMIT BUTTON ### --> <p style="text-align:center"> <input type="submit" name="submit" value="SEND MY INFO PLEASE" /> </p> </fieldset> </form> </div> </body> </html> ====================== PHP ========================== <?php // ALL THE SUBJECT and EMAIL VARIABLES $emailSubject = 'MY TEST EMAIL SCRIPTING!!!

Code Hi. I currently have php java to get my database results and limit the amount of data shown by a given value. The js includes buttons to go forward or backward in the database. Everything is all fine and dandy except I'm trying to add a very simple search for the user as well. I want the user to be able to select either "firstname" or "lastname" to search through the database and display the resulting rows based of the first three characters entered into the search criteria. I'm not sure where to start on this... Do I have to add something the js (I'm not very familiar with js), or should I add mysql_query's in the php linked file?

Hi Guy's, I've recoded allot with 3 scripts i had to my disposal. I've fixed 95% and i'm proud allready, but stuck at the following code.

The code worked before adding the encryption. Since adding the encryption I've also adding the corresponding fields for username and password into the sql database and double checked, and triple checked all the php, html form and MySQL tables and fields, but don't see any thing wrong. Can anybody else see any immediate problems with the code snippet below? If so, can you please let me know? session_start(); $salt = 'The sky is blue and all the trees are green'; $data = array_map('mysql_escape_string', $_POST); $password = sha1($data['password'].$salt); $query = " INSERT INTO customers ( first_name, last_name, address, mobile, email, username, password ) VALUES ( '{$data['first_name']}', '{$data['last_name']}', '{$data['address']}', '{$data['mobile']}', '{$data['email']}' '{$data['username']}', '$password' ) "; if(mysql_query($query)) { echo 'Your login details have been saved.'; } else { echo 'Your login details have not been saved.<br>'; echo 'Please try again later.'; } Thanks. All I am trying to do is add a record on a page without the page refreshing. For that ajax is used. Here is the code.
It does not add the record to mysql table. Can anyone tell me what I am doing wrong?

im using the floowing code to pull all alerts from the database. as you can see i have 3 types of alertsd. Profile alerts, forum alerts and topic alerts. They are sorted and placed on the screen under their respective header. However i want to limit it so it only displays 4 of each type of alert. I cant use LIMIT in the query because that would limit all alerts meaning only 4 alerts in total would show up and i just need to limit each alert type. any ideas? $alert_query = $link->query("SELECT a.a_aid, a.a_alert_type, a.a_time_alerted, a.a_fid, a.a_poster, a_alert_read, a.a_tid, c.f_name as cat_name, f.f_fid, f.f_name, t.t_name, u.u_avatar, u.u_avatar_cropped FROM ".TBL_PREFIX."alerts as a LEFT JOIN ".TBL_PREFIX."forums as f ON (f.f_fid = a.a_fid) LEFT JOIN ".TBL_PREFIX."topics as t ON (t.t_tid = a.a_tid) LEFT JOIN ".TBL_PREFIX."forums as c ON (c.f_fid = f.p_id) LEFT JOIN ".TBL_PREFIX."users as u ON (u.u_username = a.a_poster) WHERE a.a_user_name = '$user_name' ORDER BY a_time_alerted ") or die(print_link_error()); $alert_info = $alert_query->fetchAll(); $pm_alert_list = ''; $num_pm_alerts = 0; $num_forum_alerts = 0; $num_topic_alerts = 0; foreach($alert_info as $key => $val) { $alert_info[$key]['a_alert_read'] == 0 ? $color = '#f5dfaf' : $color = '#f4f4f4'; // if alert is a profile message alert if($alert_info[$key]['a_alert_type'] == 1) { $pm_alert_list .= '<dd style="background:'.$color.';" class="alert" id="alert-'.$alert_info[$key]['a_aid'].'"><p class="alert_intro">'; $pm_alert_list .= '<input type="checkbox" class="pm_checkbox" id="pm_checkbox-'.$alert_info[$key]['a_aid'].'" />'.profile_link($alert_info[$key]['a_poster']).' posted on your wall</p>'; $pm_alert_list .= '<p class="alert_time"> on '.asf_date($alert_info[$key]['a_time_alerted'],'full').'</p>'; $pm_alert_list .= '</dd>'; $num_pm_alerts++; } if($alert_info[$key]['a_alert_type'] == 2) { $forum_alert_list .= '<dd style="background:'.$color.';" class="alert" id="alert-'.$alert_info[$key]['a_aid'].'"><p class="alert_intro">'; $forum_alert_list .= '<input type="checkbox" class="pm_checkbox" id="pm_checkbox-'.$alert_info[$key]['a_aid'].'" /><strong><a href="'.$config['asf_root'].'category/'.create_url($alert_info[$key]['cat_name']).'/forum/'.create_url($alert_info[$key]['f_name']).'">'.$alert_info[$key]['f_name'].'</a></strong> has a new topic</p>'; $forum_alert_list .= '<p class="alert_time"> '.asf_date($alert_info[$key]['a_time_alerted'],'full').'</p>'; $forum_alert_list .= '</dd>'; $num_forum_alerts++; } if($alert_info[$key]['a_alert_type'] == 3) { $topic_alert_list .= '<dd style="background:'.$color.';" class="alert" id="alert-'.$alert_info[$key]['a_aid'].'"><p class="alert_intro">'; $topic_alert_list .= '<input type="checkbox" class="pm_checkbox" id="pm_checkbox-'.$alert_info[$key]['a_aid'].'" /><strong><a href="'.$config['asf_root'].'category/'.create_url($alert_info[$key]['cat_name']).'/forum/'.create_url($alert_info[$key]['f_name']).'/topic/'.create_url($alert_info[$key]['t_name']).'">'.$alert_info[$key]['t_name'].'</a></strong> has a new post</p>'; $topic_alert_list .= '<p class="alert_time"> '.asf_date($alert_info[$key]['a_time_alerted'],'full').'</p>'; $topic_alert_list .= '</dd>'; $num_topic_alerts++; } } This code works fine without the LIMIT 5, but it lists all the results.
