Something I found out recently when I updated the cakePHP core files, when accessing my 1and1 hosting using ssh I kept getting errors when using the cakePHP console. The problem was caused by the fact that by default 1and1 uses PHP 4 for the command line. This cannot be altered using .htaccess, however after a little googleing I found that using php5 on the command line does as you would expect. So to make your cakePHP console work using PHP 5, all that is needed is a little editing of one file. CORE/console/cake
Change this:
exec php -q ${LIB}cake.php -working "${APP}" "$@"
To this:
exec php5 -q ${LIB}cake.php -working "${APP}" "$@"
All console actions will then be run using PHP 5.
Recently I came across a problem, where I wanted to show a select box for zones in an address (counties or states etc.). I have a list of zones in my database and to put them all in one box would have been unusable as the list is in excess of 2000 zones. My solution to this was only show the zones related to the country selected in another select box. When the user changes the country the zones are updated. In this tutorial I will explain how I achieved this using cakePHP (1.3) and the YUI Library (3.1.1).
Ok, so we all know how useful those flash messages are that cakePHP throw at us, “you’ve done it wrong, try again”. Well as much as I like them I don’t want to be reminded of my error untill I go to a different page. The answer is to make them disapear.
Using the YUI Animation Utility, we can simply make the div containing the message close to nothing. First you need to make sure your $session->flash() is wrapped in a div if it appears.
The aim of this tutorial is to be able to pull data from your database and output it in a nice shiny data table. Although the cakePHP paginator does this perfectly well, I have been using YUI and I am not a fan of the prototype library.
The YUI Paginator control is able to send requests to the server with parameters for the page required, the DataTable control can then format that data into our shiny table.
For this tutorial I have used CakePHP 1.2 RC3 and YUI 2.6.0. I am using a “Products” controller, model and corresponding views.
Thanks should go to this post http://www.ntatd.org/mark/?p=32 by Mark Buckner (aka hydra12) describing how to use cakePHP with ExtJS DataGrid, for the inspiration and the some of the cakePHP code for this tutorial.
