PHP - Limiting String Print
I have a database of 100 lines which have echoed onto the page so each line within the database is printed. I would like to limit it to ten. However, I have tried a whole range of different loops but none of them seek to work.
Some of them print the database ten times so I have 1000 lines on the page. Can anyone advise the best method of limiting how many lines within a database are printed on the page? Similar TutorialsI have a string in the form of "word1-word2-word3-word4-word5-word-6-word7", but I want to shorten it to 5 words only. If I wanted to print a string that contains a variable that also contains an array, how would I do so? I want to put the resulting echo into a log file. Example: “These are the books: $userArray and these are the pages: $pagesArray”; With just an array, I can use print_r($array, true) to get an array formatted for use in a string (which works well for my purposes) but this doesn’t work with two arrays unless I do this manually. (Such as setting the $user_array = print_r($userArray). But I want to write a function that will take a string, potentially containing arrays (as variables), and interpolate/make them legible for humans. (Some of the arrays are also multidimensional.) But it looks like I can't even concatenate a string and an array. $string = $string . $array. gives an error, array to string conversion. I don’t understand PHP very well so please explain what is going on here. and the best way to record something like the Example above. String: NodeJs is one of the best technology Quote

How to print the largest even number? Hello, I am attempting to create a script where a user puts a text string into a form and clicking on submit. Then it adds that text string to a mysql database and gives the user a link back to it. Something like mysite.com/key.php?id=4 and when going to that link it will display the text string from the database but printed in an image. I wrote something up but I cannot get it to work. I may be a little in over my head. Any help is appreciated.
The way I coded this all to work is the user inputs the information into index.php which givekey.php inserts that into the database. I have not yet figure out how to do this in one single step. After that I wanted it to navigate directly to key.php which would display the key and the link to that page with the ?key=XX attribute. getkey.php
<?php
require_once 'dbinfo.php';
// database connection
$id = $_GET['id'];
// do some validation here to ensure id is safe
$link = mysql_connect($servername, $username, $password);
if (!$link) {
die('Could not connect: ' . mysql_error());
}
@mysql_select_db($database) or die( "Unable to select database");
$sql = "SELECT ukey FROM keycode WHERE id=$id";
$result = mysql_query("$sql");
$row = mysql_fetch_assoc($result);
mysql_close($link);
header("Content-type: image/png");
echo $row['ukey'];
?>

Edited by chrisb302, 13 November 2014 - 12:18 AM. Im not sure f this is the right spot for this or not but... I have a website that has a content box that has a fixed height and width. How would i make it so after the box is full it puts a link to read more at the bottom of it? Also images may be used as well. Its also for a wordpress blog Hi, I am wondering if it is possible to monitor how long someone is on a website for and to limit them for example: 30 minutes. An example of this would be one of those Tv Online websites which allow you to only watch 30 minutes of video time. If you try refreshing the page it will still not allow you. My question is, Is it an ip check which does this? Sorry If it such a broad topic. Nick OMG! Crafting well thought out business logic is such a PITA sometimes! I am working on an ecommerce site that sells subscriptions, books, gear, etc. Similar to a lot of online newspapers, I have a "Subscribe" button in my website mast where people can buy a subscription. After clicking on that button, the user is first presented with different subscription offers (e.g. sliver, gold, platinum), and then I have a one-page checkout form where they create an account - kind of important for an online subscription! - and they pay with a credit card. Easy! Trying to be a nice guy, I decided to add the ability to choose a subscription from my online store as well. (Presumably you want to offer as many ways for people to buy things from you as possible, right?) Well here is the issue I just discovered... What happens if a person is browsing through my product catalog, and they add multiple subscriptions to their shopping cart? Of course I would welcome the extra $$$, but I just realized that would break how people create their accounts and pay, because above I assume that ONE person, buys ONE subscription and pays for it in ONE transaction. So my questions is, "Would it be a mortal sin to limit people to buying only ONE subscription at a time if they do so while in my online store?" I would hope that people would get that, but as we know, users do some crazy stuff!! In fairness, if you went to buy a subscription at the Wall Street Journal or any other large newspaper/magazine, you would be forced to do one subscription per transaction. I am just wondering what happens if someone goes on a shopping spree in my online store, buys several books, some t-shirts, and decides he/she also wants to buy 5 subscriptions on the spot. Thoughts?
Ok so here's my code first the ajax/javascript, secondly the php. Issue i'm having is that first it wasn't entering any data into my database then eventual through much troubleshooting I figured out that if I add more then 10 variables in my INSERT INTO query it wont work. Ten or less and it works perfect. I CAN NOT figure this out?! Note, at the bottom of the php script I have the script that I would like to work, commented out, and the script that is currently working, active. You can see it only has 10 working entries. Code: [Select] function entervehicle(){ var stk = document.getElementById("stk").value var my = document.getElementById("my").value var mak = document.getElementById("mak").value var mod = document.getElementById("mod").value var mil = document.getElementById("mil").value var pri = document.getElementById("pri").value var bst = document.getElementById("bst").value var len = document.getElementById("len").value var eng = document.getElementById("eng").value var dor = document.getElementById("dor").value var tra = document.getElementById("tra").value var gvw = document.getElementById("gvw").value var inc = document.getElementById("inc").value var exc = document.getElementById("exc").value var cfo = document.getElementById("cfo").value var titl = document.getElementById("titl").value var desc = document.getElementById("desc").value var vin = document.getElementById("vin").value var pic1 = document.getElementById("pic1").value var pic2 = document.getElementById("pic2").value var pic3 = document.getElementById("pic3").value var pic4 = document.getElementById("pic4").value var pic5 = document.getElementById("pic5").value var pic6 = document.getElementById("pic6").value var pic7 = document.getElementById("pic7").value var pic8 = document.getElementById("pic8").value var pic9 = document.getElementById("pic9").value var linksubmit ="../php/entervehicle.php?stk=" + stk +"&my=" + my +"&mak=" + mak +"&mod=" + mod +"&mil=" + mil +"&pri=" + pri +"&bst=" + bst +"&len=" + len +"&eng=" + eng +"&dor=" + dor +"&tra=" + tra +"&gvw=" + gvw +"&inc=" + inc +"&exc=" + exc +"&cfo=" + cfo +"&titl=" + titl +"&desc=" + desc +"&vin=" + vin +"&pic1=" + pic1 +"&pic2=" + pic2 +"&pic3=" + pic3 +"&pic4=" + pic4 +"&pic5=" + pic5 +"&pic6=" + pic6 +"&pic7=" + pic7 +"&pic8=" + pic8 +"&pic9=" + pic9 alert(linksubmit); var entrequest = getHTTPObject(); if(entrequest) { entrequest.open("GET",linksubmit,true); entrequest.onreadystatechange = function(){ entveh(entrequest); }; entrequest.send(null); } } function entveh(entrequest){ if(entrequest.readyState == 4){ if(entrequest.status == 200){ var myPHP = entrequest.responseText; document.getElementById("adminmain").innerHTML = myPHP; } } } <?php $stk = $_GET['stk']; $my = $_GET['my']; $mak = $_GET['mak']; $mod = $_GET['mod']; $mil = $_GET['mil']; $pri = $_GET['pri']; $bst = $_GET['bst']; $len = $_GET['len']; $eng = $_GET['eng']; $dor = $_GET['dor']; $tra = $_GET['tra']; $gvw = $_GET['gvw']; $inc = $_GET['inc']; $exc = $_GET['exc']; $cfo = $_GET['cfo']; $titl = $_GET['titl']; $desc = $_GET['desc']; $vin = $_GET['vin']; $pic1 = $_GET['pic1']; $pic2 = $_GET['pic2']; $pic3 = $_GET['pic3']; $pic4 = $_GET['pic4']; $pic5 = $_GET['pic5']; $pic6 = $_GET['pic6']; $pic7 = $_GET['pic7']; $pic8 = $_GET['pic8']; $pic9 = $_GET['pic9']; require("database.php"); $tresult = mysql_query("INSERT INTO automobile_stat (stock_number,model_year, make, model, miles, price, body_style, length, description, trans) VALUES ('$stk', '$my', '$mak', '$mod', '$mil', '$pri', '$bst', '$len', '$desc', '$tra')"); /*$tresult = mysql_query("INSERT INTO automobile_stat (stock_number, model_year, make, model, miles, price, body_style, length, description, engine, doors, trans, gvw, int_color, ext_color, car_fax_owner, title_desc, main_picture_src, vin) VALUES ('$stk', '$my', '$mak', '$mod', '$mil', '$pri', '$mpri', '$bst', '$len', '$desc', '$eng', '$dor', 'tra', '$gvw', '$inc', '$exc', '$cfo', '$titl', 'img', '$vin')");*/ /*$tresult=mysql_query("SELECT * FROM automobile_stat" ); $countrows = mysql_num_rows($tresult); while($row = mysql_fetch_array($tresult)){ echo $row[stock_number]; }*/ mysql_close($linkID); ?>

Hey there - I have been trying to limit the number of comments a user can make per day on my social network. Thanks to great help on here I am getting really close, however, there are some bugs that have me banging my head against the wall. I am able to limit, but now, its 1. not limiting PER day and limiting all around ( meaning: I can't make any comments at all today ) 2. it is limiting for EVERY user as opposed to limiting a specific user Here is the code I have: Code: [Select] if(isset($_POST['commentProfileSubmit'])) { if($_POST['ProfileComment'] == "" || $_POST['ProfileComment'] == "Tell the community what's on your mind...") { $valid = false; $error_msgs_comments[] = "Whoops! You forgot to write your airwave."; }else{ if($_POST['ProfileComment'] == "" || $_POST['ProfileComment'] == "Leave ".$prof->first_name." a comment here...") { $valid = false; $error_msgs_comments[] = "Whoops! You forgot to write your comment."; }else{ /* if the person signed in is NOT the profile */ $query = "SELECT * FROM `cysticUsers` WHERE `id` = '" . $prof->id . "'"; $request = mysql_query($query,$connection) or die(mysql_error()); $result = mysql_fetch_array($request); $max_post_per_day = 5; $Email = $result['Email']; $check_profi = $result['check_profi']; $check_reply = $result['check_reply']; if($prof->id != $auth->id && $check_profi == 'checked' && $max_post_per_day < 5) { $to = $Email; $subject = "$auth->first_name $auth->last_name commented on your profile on CysticLife"; $message = "$auth->first_name $auth->last_name commented on your profile on CysticLife: <br /><br />\"$body\"<br /><br /> <a href='http://www.cysticlife.org/Profile_build.php?id=" . $prof->id .

Trying to use the "Excerpt or Content Word Limit in WordPress: Redux" code to limit my Amazon product description content but to no avail. Getting the "Fatal error: Call to undefined function content() in index.php on line 36". The following is the code in the index.php file that makes the call: " <div class="post-content"> <?php content(30); ?> <!-- <?php the_post_excerpt($excerpt_length=30); ?> --> </div><!-- POST CONTENT --> " The functions.php file is quite large but I attached it so anyone who would like to take a look at it. Can anyone tell why it's not finding the function 'content'? Thanks! Following on from the excellent help in the thread at http://www.phpfreaks.com/forums/php-coding-help/using-a-generated-row-number-in-another-query I have another question regarding the League Standings that are generated there. I want to have another version that limits the records to the last 5 games for each team. Just using 'LIMIT 5' would return the first five teams and all their records but I want it to retrieve all of the teams and each teams last five records (games). The easy way would be to restrict a the dates but as games get postponed and moved using WHERE with a specific date would not guarantee the same number of games for each team. There is the possibility that this could be done via the query but I have not come across anything in some quite extensive searching (although, once again, I do not know if I am using the right search terms!) so I assume PHP would, once again be the saviour! Thanks in advance for any suggestions. Steve hello all - I have a social network for the cystic fibrosis community and we've had a spammer the passed couple of days. I have captchas set up and they work well, but in addition to those I want to limit the amount of blogs a user is allowed to post a day. I have been able to count and echo out the amount a user has made, but for some reason, when I use an if statement to stop the blog from posting it still post's. I have been working on this going on hour 8 now and need some major help Thanks in advnace. Here is my code Code: [Select] if(isset($_POST['subComposeBlog'])) { $query = "SELECT COUNT(`id`) FROM `cysticBlogs` WHERE `Author` = '".$auth."' && `date` = NOW() && `status` = 'active'"; $request = mysql_query($query,$connection) or die(mysql_error()); $result = mysql_fetch_array($request); $valid = true; if($_POST['Category'] == "null") { $valid = false; $error_msgs[] = "Whoops! Please select a category for this blog."; } if(empty($_POST['blogTitle'])) { $valid = false; $error_msgs[] = "Whoops! Cannot submit a blog without a title,how are you going to attract people's attention to read your masterpiece?"; } if(empty($_POST['blogBody'])) { $valid = false; $error_msgs[] = "Whoops! Cannot submit a blog without a body,that would not be a blog now would it?"; } if($result['COUNT(`id`)'] > 3) { $valid = false; echo "Whoops! You can only write three blogs per day due to spam"; } if($valid) { $query = "INSERT INTO `cysticBlogs` ( `blogTitle`, `blogBody`, `date`, `time`, `Author`, `Category` ) VALUES ( '" . mysql_real_escape_string($_POST['blogTitle']) ."', '" . mysql_real_escape_string($_POST['blogBody']) ."', '" . date("Y-m-d") ."', '" . date("G:i:s") ."', '" . $auth->id ."', '" . mysql_real_escape_string($_POST['Category']) ."')"; mysql_query($query, $connection) or die (mysql_error()); header("Location: BlogsSecurity.php"); } } I've got a somewhat simple problem I think.. I'm working on a uni practical, and one of the checkpoints is to limit the number of incorrect login attempts to 2. I know I could do this very easily with session variables, however on the practical sheet, it says that we're not allowed to modify any of the partially implemented code. So I was wondering, what other ways are there to track the number of incorrect logins? If it comes to it, I will just use session variables, as it's pretty much the most sensible way I'd imagine.. but would like to know of any other possible ways.. Cheers Denno $text = "this is a lot of effing text" what i want to do is limit it to the 10 characters so it gives back $stext = substr($text, 10); <-- this is how i thought it would work echo " $stext"; Hi, I'm having a bit of trouble with returning data from the database. It brings back the images etc... correctly, but I need to be able to limit it to two images per, line and then to carriage return. Or using CSS to position them with the correct padding etc...

)));
// Calculate the offset for the query
$offset = ($page - 1) * $limit;
// Some information to display to the user

My question is what would be the best way incorporate this into my php file so that I am able to display a limit number link by page so that not all of the results are listed on the same page? If that is even possible.
I've got a typical form with an input type="file" for users to upload photos to my site (2mb max to be exact). If you view my code below, you'll notice that I set a variable as the uploaded file's size, and a variable for the max file size I want in bytes. When making sure that the uploaded file's size is LESS than the limit size I set, it should push an error. However, I've noticed that my variable $uploadSize that is supposed to grab the upload file size is only returning "0" (zero). I've tried var_dump($_FILES) to see what was going on and it shows the array with the proper name of the uploaded file, etc. but the file size returns 0. So any file size I upload will bypass my test to see if the file size is less than the limit size. I've tested uploading images 2mb or less and the photos have successfully been queried, moved and resized. However, if I try and upload images LARGER than 2mb, the form still queries all the inputted data into the database but the image isn't successfully moved. I've used this same form and approach on a previous project and I didn't have any trouble. Can I get your guys' eyes on this and see if I'm missing anything small? Code: [Select] <?php if(isset($_POST['submit'])){ // ------------------------------------------------------------- // // A. SET VARIABLES // A1. set variables for inputted data $first = filter_var($_POST['first'], FILTER_SANITIZE_STRING); $last = filter_var($_POST['last'], FILTER_SANITIZE_STRING); $email = filter_var($_POST['email'], FILTER_SANITIZE_STRING); $email2 = filter_var($_POST['email2'], FILTER_SANITIZE_STRING); $name = filter_var($_POST['name'], FILTER_SANITIZE_STRING); $description = filter_var($_POST['description'], FILTER_SANITIZE_STRING); // A2. set variables for uploaded submission $uploadPath = $_FILES['uploadFile']['tmp_name']; $uploadSize = $_FILES['uploadFile']['size']; $uploadLimit = 2097152; /* 2mb max file size */ // A3. create error array $errors = array(); // ------------------------------------------------------------- // // B. VALIDATE FIELDS // B1. validate required fields if (empty($first)){ array_push($errors, 'first'); } if (empty($last)){ array_push($errors, 'last'); } if (empty($email)){ array_push($errors, 'email'); } if (empty($email2)){ array_push($errors, 'email2'); } if (empty($name)){ array_push($errors, 'name'); } // B2. validate emails if ($email != $email2){ array_push($errors, 'emailmismatch'); } if (!filter_var($email, FILTER_VALIDATE_EMAIL)){ array_push($errors, 'invalidemail'); } // B3. validate uploaded image file size if ($uploadSize > $uploadLimit){ array_push($errors, 'filesize'); } // ------------------------------------------------------------- // // if no errors, continue query if (sizeof($errors) == 0){ // continue query } } ?> Code: [Select] <form method="post" enctype="multipart/form-data" id="submit-form"> <label for="first">First Name:</label> <input name="first" type="text" value="<?php echo $first; ?>"<?php if(in_array('first', $errors)){ echo ' class="error"'; } ?>> <label for="last">Last Name:</label> <input name="last" type="text" value="<?php echo $last; ?>"<?php if(in_array('last', $errors)){ echo ' class="error"'; } ?>> <label for="email">Email Address:</label> <input name="email" type="text" value="<?php echo $email; ?>"<?php if(in_array('email', $errors)){ echo ' class="error"'; } else if (in_array('emailmismatch', $errors)){ echo ' class="error"'; } ?>> <label for="email2">Confirm Email Address:</label> <input name="email2" type="text" value="<?php echo $email2; ?>"<?php if(in_array('email2', $errors)){ echo ' class="error"'; } else if (in_array('emailmismatch', $errors)){ echo ' class="error"'; } ?>> <br><br><br><br> <label for="name">Your Photo Name:</label> <input name="name" type="text" value="<?php echo $name; ?>"<?php if(in_array('name', $errors)){ echo ' class="error"'; } ?>> <label for="description">Describe The Photo: <span class="optional">(optional)</span> <div class="right"><span class="optional">300 characters max</span></div></label> <textarea name="description" onKeyDown="limitInput(this.form.description,this.form.countdown,300);" onKeyUp="limitInput(this.form.description,this.form.countdown,300);"><?php echo stripslashes($description); ?></textarea> <label for="upload">Photo Image: <span class="optional">(.JPG's only, max 2mb file size)</span></label> <input type="hidden" name="MAX_FILE_SIZE" value="2097152"> <input id="uploadFile" name="uploadFile" type="file"<?php if(in_array('badimage', $errors)){ echo ' class="error"'; } ?> /> <input type="submit" name="submitFeature" class="submit" value="Submit Your Feature"> </form> I would like to know the best practice to achieve the following: I have a list of dates related to live events for performing artists. When someone views the web page that contains a section to display the dates, I would only want to show the dates from today into the future and not show any dates from the past. What is the best way to accomplish this? Thanks in advance... |
