I built a homepage for my WordPress site from scratch, copying the style of the theme Reflex (which I actually bought). I'm doing this because this way the site is faster, and uses a lot less bandwidth.
Original site and my build
But, I'm having trouble getting the featured images, I wrote some quick code just to work it out:
<img src="'.$thumb_img.'-200x200.jpg">
I add "-200x200" at the end of the url which I got from the database. I understand this is not the best way to do this, so the question is: what's the best practice here?
Also: am I right in rewriting WordPress' frontend for performance? Is there a better approach or solution that you can think ok?
Thanks in advance!
Try this:
<?php the_post_thumbnail( array(200, 200) ); ?>
or, if you are not in the loop, try this:
<?php
$post_id = 54; //the post id that you want to display
echo get_the_post_thumbnail( $post_id, array(200, 200) );
?>

I have a Wordpress blog and I'm developing a backend application using Cakephp.
I want to develop the blog's contact form using cake (since the entered information will be available from the backend app).
Right now, I tried including the cake view into wp using ajax. The problem with this approach is that I either use a Js->submit, which makes attaching files to the form quite complicated, or I use a Form->submit, which makes displaying validation errors problematic. Also, it creates problems with the recaptcha plugin not showing up.
Is there a way of integrating the form using php? I don't need authentication (it is a public form), but I need to be able to show validation errors on the form and upload files on the form.
Actually, you can load any website into a string using CURL, if you load en empty page with a placeholder from your wordpress, you can then use it as your layout
<?php
$url = "http://www.yourdomain.com/emptypage";
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
$output = curl_exec($curl);
curl_close($curl)
$placeholder = "{{CONTENT}}"
$placeholderPos = strpos($output,$placeholder);
$beginning = substr($output,0,$placeholderPos);
$end = substr($output,$placeholderPos+strlen($placeholder));
echo $beginning;
////// your form //////
echo $end;
?>
You may have to deal with relative path after that, but this should get you started.
So, I finally found a way I think is the best since it uses cake classes.
I created a file new_file.php on webroot that is basically a copy of index.php but instead of using a generic request it requests the specific page I'm looking for:
$Dispatcher = new Dispatcher();
$Dispatcher->dispatch(new CakeRequest('CONTROLLER/ACTION'), new CakeResponse(array('charset' => Configure::read('App.encoding'))));
Of course, you'll have to change 'CONTROLLER/ACTION' to whatever your controller is.
After that, you only have to include the file in a WordPress plugin.
There is only one more change. There are some methods that conflict with WP declarations. PHP will complain when you include the above file. You have to find those method and wrap them into an if to make sure the method is not redeclared. This can break some functionality like localization (function __()) but it is ok if what you are including is not a very complex cake application.
if (!function_exists('methodName')) {
Hopefully the last issue will be solved once Cake 3 is out with namespaces support.
For some reason my cakephp application is not showing any of the queries made to the database. It prints the table fine, but there are not records. What could cause this?
Check to make sure you are pulling the records correctly.
$models = $this->Model->find('all');
// or
$this->Model->recursive = 0;
$this->set('models', $this->paginate());
Then when you add them in the view, be sure you are looping through them correctly:
foreach ($models as $model) {
echo $model['Model']['field_name'];
}
UPDATE
To show the SQL statements, be sure you have the following set in core.php
Configure::write('debug', 2);
Also, in the Layout, besure you have this included someone between the <body> and </body> tags:
<?php echo $this->element('sql_dump'); ?>
I assume that you are getting an empty table with just the "Nr","Query","Error", etc. column headers?
You are getting the empty table because you have "Configure::write('debug',0);" set somewhere before you have "Configure::write('debug',2);" set. Find the first instance of it and delete it or change it to "2".
I know that you have long since fixed this problem but hopefully it helps somebody else in the future.
The CakePHP debug kit can help you. After you install it, you will notice a small (pie-chart) icon on the top right of your CakePHP pages. Clicking on that will allow you to see various useful information, and most importantly for this issue, all the SQL queries that occurred in the back-end upon the page loading.
I faced a similar problem in cakephp. I found that debug($variable) has limitation to the content size. Since you are fetching huge sized content from database, it is not able to print. Try doing print_r($variable) instead. To format it properly, you can do like this
echo "<pre>".print_r($variable)."</pre>";
I am new to cakephp and I think I've run into my first problem because I need 2 $content_for_layout in my default layout, like this:
<div id="left_collumn">
<?php echo $content1_for_layout ?>
</div>
<div id="right_column">
<?php echo $content2_for_layout ?>
</div>
I've searched this group and found a thread that suggest using this : http://bakery.cakephp.org/articles/rtconner/2007/08/28/anything_for_layout-making-html-from-the-view-available-to-the-layout and even though I followed the instructions for some reason this is what I always get :http://img38.imageshack.us/img38/3246/sshot1duh.jpg
Do you have any idea why this is happening?
I am not sure what you are trying to do, but maybe you could use an element instead...
http://book.cakephp.org/view/1081/Elements
Read about plugins, thats not the way! Lear to make your own plugin!
Yeah you should use elements instead. Try to go with the rules of the framework whenever you are working on it. There is no need to change the way how Cake PHP handles it, rather using the solutions which framework offers. Use Elements.

(I know there's a couple of other reverse-routing-slugs questions on this site, but I'm not having much luck relating the answers to my particular issue, so I'll ask my more specific question...)
I am building a site whose URLs now need to be slug-based, i.e. what was initially news/item/1 now has to have the URL news/firstnewsitem. And so on for a number of other controllers. I can easily get these addresses to work, and maybe even not stomp on my existing utility actions, with something like:
Router::connect('/:controller/:slug',
array('action'=>'item'),
array('pass'=>array('slug'), 'slug'=>'[^(index|add|edit|view|delete)]')
);
However, the reverse routing of these new links seems to be a non-starter: Cake is still generating such links as news/item/3. It seems optimistic to hope that a slug-based URL would automagically happen, but is there any array that I can pass in my Html->link parameters that will create the :controller/:slug format I'm looking for? Or do I have to cut my losses and back away from reverse routing at this point?
There's a pretty decent plugin for handling slug-based routing here:
https://github.com/jeremyharris/slugger
If you used this, you would be able to create links something like this
$html->link("some item", array(
'controller'=>'items',
'action'=>'view',
'Item'=>$item['id']
));
and that would output a link to /items/view/slug-for-your-item
Looking to figure out how to measure the total PHP execution time of a CakePHP site. It looks like in 1.2 this was included in the rendered HTML as a HTML comment when in debug mode, but this is not happening on my 1.3 site, and in any case I want it as an element I can output to the user, not a comment.
I can do this easily in regular PHP using microtime() but I'm not sure where to add the code in CakePHP, and I suspect it might have a more robust execution timer anyway. Ideas?
Just in case anyone else is curious, I solved this by adding the following code to my layout.ctp. You could also do this in the controller and pass it in as a variable, which might be a little more classic MVC-friendly, but I wanted this on every page of the site without duplicating code in each controller.
Page rendered in <?php echo round((getMicroTime() - $_SERVER['REQUEST_TIME']) * 1000) ?>ms.
Use Debug Kit. Among other functionality, you can grab the total execution time via
DebugKitDebugger::requestTime()
This may not be the "right" way to do it, but you can add the following PHP code back into app/webroot/index.php (at the very end). Then if you have debug on > 0, you'll get the old 1.2 functionality back.
if (Configure::read() > 0) {
echo "<!-- " . round(getMicrotime() - $TIME_START, 4) . "s -->";
}
