I am using ajax in my cakephp application by using JS helper.so I do not required to write jquery code.
Js helper automatically add the code in my file.Following is the line by which JS helper write the code.
echo $this->Js->writeBuffer(array('cache'=>true));
When I set the true value of cache attribute,every time a new js file created in js folder and a new script is added in my code in following manner.
<script type="text/javascript" src="filename.js"></script>
But when I change the cache value to false,all the js code added in my file line by line.
Now my question is, which way is best way by which,page execution fast.
And my second question is that when I set true value of the cache, js file add only once, right now js helper add the js file again and again,when page is reload or refresh.
For the record this question could have been worded far better.
First question, execution speed: Saving a new file for every bit of JS probably isn't the way to go. Hopefully the code below should explain a better way and render your second question moot.
// In /app/View/Layouts/default.ctp
...
<head>
...
<?php echo $this->fetch('script'); ?>
...
</head>
<body>
...
<?php echo $this->Js->writeBuffer();
...
</body>
Once that's in place, you can add a script file to your views or layouts with
<?php echo $this->Html->script('scriptname', array('inline'=>false)); ?>
(note no .js extension)
Or add custom Js:
<?php
$customJs = "alert('Hi!');";
echo $this->Html->scriptBlock($customJs, array('inline'=>false));
?>
Hope that helps.

I am using CakePHP 1.3. In app/views/layouts/default.ctp I am using this:
<?php echo $content_for_layout;?>
According to CakePHP Application Development, by Ahsanul Bari and Anupom Syam,
"This line is mainly responsible for placing controller-rendered view
contents inside the layout. We must include this to tell Cake where to
place the action-specific controller-rendered views."
I was trying to figure out how to modify the content of $content_for_layout. But I guess that is not the kind of variable that I am supposed to modify to modify the layout. What I am trying to accomplish is to either modify $content_for_layout or create a new layout to customize some elements for an A/B testing experiment. Could you help me to better understand how to manipulate $content_for_layout? Thank you.
UPDATE 1:
I am configuring an A/B testing experiment. I have this in app/views/layouts/default.ctp:
<body>
..........
<div id="split-test-homepage-content-original">
..........
<?php echo $content_for_layout;?>
..........
</div>
<div id="split-test-homepage-content-redesign">
..........
<?php echo $content_for_layout;?>
..........
</div/>
</body>
With CSS I am hiding/showing either split-test-homepage-content-original or split-test-homepage-content-redesign depending on the version that the split test will show. But I am having problems because $content_for_layout is being rendered twice. Even though visually people only see one version but behind the scenes the page has $content_for_layout loading twice on the same page. This is causing all kinds of problems to me such as duplicate forms, JavaScript elements not working correctly as a result of duplicate variables, etc. What I want to do is to modify what $content_for_layout does for <div id="split-test-homepage-content-redesign">. One option I am considering is to use JavaScript so that in the jQuery(document).ready(function($) { section I can do something in the experiment so that if a variable contains a specific boolean value, I show one version or the other. Something like this:
if(javascriptvariable==true){ then use the following HTML for the view:
<div id="split-test-homepage-content-original">
..........
<?php echo $content_for_layout;?>
..........
</div>
else, the Javascript will take care of not displaying the above, but this:
<div id="split-test-homepage-content-redesign">
..........
<?php echo $content_for_layout;?>
..........
</div/>
Does the JavaScript approach make sense to you or should I do something about creating new layouts or modifying what $content_for_layout does? Thank you.
Duplicating content was definitely asking for trouble. I used a much better approach to manipulate CSS classes and ids only without duplicating content.
I am trying to override the front page node, however after following the guide from the official site, it's not working.
Guide: https://www.drupal.org/node/1585528
I have taken node.tpl.php and renamed it to node--front.tpl.php and made changes to the layout, saved and cleared cache. The changes are not being displayed.
Now if I edit node.tpl.php directly it shows the changes, anyone know what I am doing wrong to override specific node templates?
EDIT:
I want to move the title below the image being displayed in the front page.
See below: Moving the title block under the content block, moves the title down as I want it to do, however how do I specify this for just the front page and not all nodes? (renaming node.tpl.php to node--front.tpl.php does not work as mentioned above)
In node.tpl.php: (title block)
<?php print render($title_prefix); ?>
<?php if (!$page): ?>
<h2<?php print $title_attributes; ?>>
<?php print $title; ?>
</h2>
<?php endif; ?>
<?php print render($title_suffix); ?>
(content block)
<div class="content clearfix"<?php print $content_attributes; ?>>
<?php
// We hide the comments and links now so that we can render them later.
hide($content['comments']);
hide($content['links']);
print render($content);
?>
To override the node template for particular node, you need to override the default node.tpl.php. For this copy the existing node.tpl.php file to node--{node_id}.tpl.php.
If you want to override the page template only for front page then you can create page--front.tpl.php file and copy the page.tpl.php file and then modify it as per your requirement.
Still you have issues, then use hook_preprocess_page() in template.php and use dpm() function to find the theme_suggestions that will give the sequence of execution of templates file.
you can use node-{nodeid}.tpl.php
It may help you.

i am working on a Cakephp 2.x .. right now i am loading my js and css files like this
View/Layout/default.ctp
<?php echo $this->fetch('css'); ?>
<?php echo $this->fetch('script'); ?>
<?php echo $this->fetch('scriptBottom');?>
and in each view file i am doing this because there are some pages i am loading different css and js files
for example
View/users/index.ctp
echo $this->Html->script('libs/modernizr.custom',array('inline' => false));
$this->Html->css('reset3860.css', null, array('inline' => false));
echo $this->Html->script('libs/jquery-1.8.2.min', array('block' => 'scriptBottom'));
now the first problem i am facing right now is when i have to write js at the bottom of view page for example if i am submitting a form through ajax .. i can't write at the bottom of the index page ... because if i write there the js will go at the middle or center of the page so now what i do is i go the default.ctp and write there..
so i want to write at the bottom of the index page so it can easily managable and i can see it well what i am doing
the second question is what is the best way to manage all this ... or is there a way that i can make one file of cs and js ... in which there is only the css and js files are loaded ..and then i include that file in my default . ctp page
You should place scriptBottom block at the bottom of your layout, after content block:
<body>
<?php
echo $this->fetch('script');
echo $this->fetch('content');
echo $this->fetch('scriptBottom');
?>
</body>
And then in your views (notice - NO echo):
$this->Html->script(
'libs/jquery-1.8.2.min',
array('block' => 'scriptBottom')
);
$this->Html->scriptBlock(
"alert('Boom!');",
array('block' => 'scriptBottom')
);
here is very good concept and also i have applied in one of my application, it is working very well
it compatible with CakePHP 2.1, and packaged it as a plugin. And also upgraded the CSS compression from CSSTidy to the more recent and better maintained CSS Min.
The plugin is quick and easy to install. The installation instructions are somewhat long - but that's just to provide clarity.
for detail view you can refer Detail link Cakephp.org also you can see the plugin document and how to use it in your appliation
I've just started using cakephp elements and they're awesome (I used to use include).
I have an element gallery and an element called comments (for a certain page) and for them I have some javascript code attached to both of them. Do you have any suggestions on how I could include that javascript code in the element? If I simply add it like that it will load javascript before loading the html after the element and I don't think it's very wise.
You could put the Javascript code directly into the element file, or put the Javascript code in into your webroot folder, <cake directory>/app/webroot/js/ and include the file in your layout by using the HTML helper:
echo $html->script("myCode");
If you're worried about the Javascript code executing before the page has completely loaded, then use window.onload or $(document).ready() if you're using JQuery.
If I understand you correctly, you want to have JS specific to a page loading in the header when you call a certain element, but that the JS could be different for each element. You also want the JS to be referenced at the beginning of your HTML document.
This is actually quite easy to do. Just make sure that you have <?php echo $scripts_for_layout; ?> in you <head> tag in the layout you are using.
Then, within the element, just do:
<?php $this->Html->script("js_file", array("inline"=>false)); ?>
js_file is the name of your JavaScript file in app/webroot/js/. In this case, the file would be called js_file.js but you must leave off the .js when referencing it as above.
It doesn't matter where abouts in the element file you put this because the "inline"=>false part ensures it won't actually appear at that stage in the code. Instead, it will appear in the <head> wherever you put <?php echo $scripts_for_layout; ?> in your layout.
In cakephp 3 instead of array('inline' => false) you should use array('block' => true) if anyone is looking for that answer like I was.
How do you link css files and javascript/jquery files to a controller/view??
I am using CakePHP_1.3 and have located the following code online, but I cant seem to figure out where to put this, and secondly, where to place the css file named css_file.
<?php $this->Html->css("css_file", null, array("inline"=>false)); ?>
Any help appreciated guys...
You would put the CSS file in:
app/
webroot/
css/ <-- here
You would put the line of code in your default.ctp layout. This is located in (1.3):
cake/
libs/
view/
layouts/
default.ctp <-- copy this to app/views/layouts/
Then open that up app/views/layouts/default.ctp and look at the HTML. You'll see where Cake is already using this command. Simply replace the filename with the file you added. Do not add the .css to the end when you add the line of code.
you use echo $this->Html->css('css_file_name_without_the_extension'); and echo $this->Html->script('same') in the view
Based on your question, it sounds like you were asking how to do this on a view-by-view basis.
This is where $scripts_for_layout comes in useful.
You just need to make sure that it's in your <head> tag in /app/views/layouts/default.ctp as <?php echo $scripts_for_layout; ?>
Then, you can literally add the code you included in your question into any of your views, at literally any point you like. Because you have 'inline' => false it won't actually appear at that position in the view:
<?php $this->Html->css("css_file", null, array("inline"=>false)); ?>
...and you'll find that css_file.css is automatically linked in your <head> whenever that particular view is loaded. This is a great way to only load specific CSS files on a per-view basis when they're needed, yet make sure they appear in the <head> tag where they should be.
This also works for JavaScript as follows:
<?php $this->Html->script("js_file", null, array("inline"=>false)); ?>
If you want to have one or more CSS files loaded in all views, just put a shortened version your code in the <head> of default.ctp as follows:
<?php echo $html->css(array('each','one','of','your','css','files'));
Or, again, for JavaScript:
<?php echo $html->script(array('each','one','of','your','js','files'));
Don't include the .css or .js extension in the array.
