  • PHP form validation submit problem?

    - by TaG
    My code is suppose to save a year like 1999 to the mysql database but it wont. It will check to see if the user has entered only numbers and is at least 4 numbers long or if nothing has been entered correctly but it wont save the correct year? How can I fix this problem. Here is the PHP code. if(isset($_POST['year']) && intval($_POST['year']) && strlen($_POST['year']) == 4) { $year = mysqli_real_escape_string($mysqli, $purifier->purify(htmlentities(strip_tags($_POST['year'])))); } else if($_POST['year'] && strlen($_POST['year']) < 4) { echo '<p class="error">year is not correct!</p>'; } else if($_POST['year'] == NULL) { // do something }

  • Show parts of the result of an SQL statement using PHP

    - by mouthpiec
    I have an SQL query which returns a set of data (around 40-50 tuples). I would like to display the results 5 at a time on an HTML page using PHP. I already managed to have the right SELECT statement, but i am having problems to display the results 5 by 5 using a "more" button. Can you please help? Note that every time i call the query, the data is being randomized, so it is not possible to set limits and call the query again. I have to find the method to store the results somewhere, and then show them 5 by 5.

  • How to self-update PHP+MySQL CMS?

    - by SaltLake
    I'm writing a CMS on PHP+MySQL. I want it to be self-updatable (throw one click in admin panel). What are the best practices? How to compare current version of cms and a version of the update (application itself and database). Should it just download zip archive, upzip it and overwrite files? (but what to do with files that are no longer used). How to check if an update is downloaded correctly? Also it supports modules and I want this modules to be downloadable from the admin panel of cms. And how should I update MySQL tables?

  • mysql PHP query question

    - by camran
    Ok, i have a problem here... I am sending values of drop down lists via ajax to this PHP file. Now I want to search a mysql database using these values, which I have managed to do, BUT, only if I set the values to something... Take a look: $query = "SELECT * FROM cars_db WHERE price BETWEEN '$cars_price_from' AND '$cars_price_to' AND year BETWEEN '$cars_year_from' AND '$cars_year_to' AND mileage BETWEEN '$cars_mileage_from' AND '$cars_mileage_to' AND gearbox = '$cars_gearbox' AND fuel = '$cars_fuel'"; now, what if the user doesnt select any "price_from" or "year_from"... The fields are only optional, so if the user doesnt enter any "price from" or "year from", then the user wants ALL cars to show... Do I have to write a query statement for each case or is there another way?

  • How do I log the raw HTTP headers with a PHP script?

    - by php
    I'm using a cURL script to send POST data through a proxy to a script and I want to see what raw HTTP headers the cURL script is sending. List of things I've tried: echo curl_getinfo($ch, CURLINFO_HEADER_OUT) gives no output. file_get_contents('php://input') gets some HTTP headers but not all. print_r($_SERVER) also gets some HTTP headers but not all (I know this because there should be a X-Forwarded-For header and there isn't) Printing all superglobals ($_POST, $_GET, $_REQUEST, $_FILES etc) still doesn't show the raw HTTP headers. http_get_request_headers(), apache_request_headers(), $http_response_header, $HTTP_RAW_POST_DATA aren't outputting everything. Help?

  • PHP inheriting/extending a particular instance of an Object

    - by delta9
    Is there any way to force PHP to extend an existing/particular (and for that matter, already instantiated) instance of an object? This imaginary code should explain what I am wondering: class Base { public $var; function __construct($var){ $this->var = $name; } } class Extender extends Base { function __construct($parent) { parent = $parent; } } $base = new Base('yay!'); $extender = new Extender($base); echo 'Extended base var value: '.$extender->var.'<br/>'; Output (would be): Extended base var value: yay! To be clear, I am wanting to instantiate an object that extends a PARTICULAR INSTANCE of another object, one that has already been instantiated. I am aware that I can pass a reference to an object to another object (via it's constructor function) and then add it as a property of the receiving object, I'm wondering if there is a real way to do this?

  • PHP find if file data is an image

    - by Christian Sciberras
    Imagine I have some file data in a variable $data. I need to determine whether it is an image or not. No need for details such as corrupt images etc. Firs thought would be getting the file mime type by looking at the magic number and then see whether "image" is in the mime type. No such luck, even if I have a "file extension to mime type" script, I don't have a reliable way to get mime from magic number. My next option was to have a reasonable list of image file magic numbers and consult them. However, it relatively difficult to find such magic numbers (gif for instance has different magic numbers, some of which could pretty rare - if memory serves me right). A better idea would be some linux program which can do this kind of thing. Any ideas? I'm running RHEL and PHP 5.3. I've got root access - ie able to install stuff if needed. - Chris.

  • Complex class using PHP soapserver mapclass

    - by user559343
    Hi all, I need to create a server for processing SOAP requests. I have the wsdl and xml specifications, but I have a doubt: the xml elements are pretty complex, they are not simple type, but they have parent/child relationships (e.g. I have a Book class with an author subclass). How can I map this to PHP classes? In this example, should I create an author class i.e.: class Author { public $name; public $surname; } and then class Book { public $author; } will $author be a class of type Author? Or a typed array? Any help will be appreciated Thanks and happy new year!

  • PHP callback function not being called

    - by Industrial
    Hi everyone, I've got the following code: function _callback_memcache_failure($host, $port) { print "memcache '$host:$port' failed"; } $this->memcache = new Memcache; $this->memcache->addServer('192.168.1.35', '11211', 0, 50, 10, TRUE, _callback_memcache_failure('192.168.1.35','11211')); The server is online and running (verified!), but the Failure callback function is being called at each connection. Why is that? Reference: PHP documentation: Memcache::addServer - failure_callback Allows the user to specify a callback function to run upon encountering an error. The callback is run before failover is attempted. The function takes two parameters, the hostname and port of the failed server .

  • PHP: Iterate through folders and display HTML contends

    - by Mestika
    Hi, I’m currently trying to develop a method to get a overview of all my different web templates I’ve created and (legally) downloaded over the years. I thought about a displaying them like Wordpress is previewing it’s templates view a small preview windows, displaying the concrete file with styles and everything. How to divide them into rows and columns and create AJAX modal window open on preview and pagination and so on I believe I can manage, but it is the concept itself about iterate over several folders then find all index.htm / index.html pages and displaying them. I’ve not worked very much with directories in PHP and the only references and code stumps I’ve found so far is just to list all the files in a certain directory like, what it contains. I would be really grateful if someone knew about a script, a function, snippet or just could get me a nudge in the right direction to create such a (probably simple) preview function.

  • Anyway to improve my gzip PHP method?

    - by Joe
    I Gzip my pages currently like so: <?php ob_start("ob_gzhandler"); //my page content ob_flush(); ?> However, I read a comment somewhere, earlier on, that this method uses a lot of memory, and I know that my website has been using a lot of memory on my virtual private server, so I thought it would be nice if I knew a way to reduce memory usage. I tested my site with an online gzip tester which says my websites are sending gzipped pages, so my gzip method works, but the main obviously I'm looking for a less memory intensive option, if any. I appreciate all suggestions. :) Oh and merry christmas ;P
