I have this situation.
Three 'section' elements, on each one i load a view
<section class="col-md-12 col-sm-6">
<?= $this->load->view('folder/view1',NULL,TRUE); ?>
</section>
<section class="col-md-12 col-sm-6">
<?= $this->load->view('folder/view2',NULL,TRUE); ?>
</section>
<section class="col-md-12 col-sm-6">
<?= $this->load->view('folder/view3',NULL,TRUE); ?>
</section>
I can delete, move or edit the view on top and the one on the bottom, but not the view in the middle, if I do so, the browser return me a blank page without errors.
I have enabled all error logs, there is nothing.
Every single view got their tags and php code perfectly idented and closed.
That one is the only one giving me troubles.
What could be the problem?
I would use firebug/ console to see if the view resource is found, or something else related to fetching the asset.
The three includes i´ve posted before are inside another one,
I save the view as cache, for this, I difined the result as a variable and send in to the browser.
$string=$this->load->view('main/mainview',$data,TRUE);
echo $string;
but i skiped an echo $string to send it to the browser, because the last parameter of load->view is false for default but in this way it must be TRUE
i´m still confused about what changes view2 does to avoid this parameter, but after solving it i can edit all file properly.
If someone considers this answer as useless i will delete it as fast as possible
Thanks for your time.

Hey fellow WordPress dev's / php masters. Long story short, I am using WordPress (and I never use WordPress - sorry!) and when I go to view the individual post rendered from single.php, the 'have_posts()' function is returning false. The template is rendered and I am not having any issues with the template rendering, I am simply having an issue with 'have_posts()' showing false and not outputting the blog post.
I downloaded WordPress 5.0.3, am running on MAMP and have used this method previously without any issues. All in all, I am trying to really keep my template files organized and I am using get_template_part to retrieve sections of the theme.
My current structure is:
single.php -
<?php
get_template_part('template-parts/blog/_single/blog-post-banner'); // Renders perfect
?>
<div class="light-grey">
<div class="container">
<div class="row no-margin">
<div class="col s12 l9 mb-0-l">
<?php get_template_part('template-parts/blog/_single/blog-post'); // Renders perfect ?>
</div>
<div class="col s12 l3 mb-0-l">
<?php get_template_part('template-parts/blog/side-bar'); // Renders perfect ?>
</div>
</div>
</div>
</div>
And of course the real culprit the blog-post partial -
<?php
if (have_posts()) :
the_post(); ?>
<div class="row no-margin">
<div class="col s12 no-margin relative">
<img src="<?php the_post_thumbnail_url('medium_size'); ?>" alt="<?php the_title(); ?>" class="block">
</div>
<div class="col s12">
<div class="white p-2-s p-3-l">
<?php the_content(); ?>
</div>
</div>
</div>
<?php else :?>
<div class="col s12 no-margin">
<div class="white p-2-s p-3-l"><p>Sorry, we couldn't find the post you were looking for.</p></div>
</div>
<?php endif; ?>
Again, the templates are rendering perfect but the 'have_posts()' is returning false and spitting out my 'else' part of my statement. I have used this method in another template and it worked perfectly before (although I will admit, I love to develop in node and WordPress and php have really made me beat my head against the wall at times lol). Is there something I missed?
I have checked my functions.php which I have written from scratch, and there isn't a single thing in there that might affect the post but if you need to see it, I would be happy to share it (I have disabled each portion of the functions.php to check if it would help and no luck). I don't have any plugins added, not even the default included ones (I am a dork that wants to build most everything from scratch so I know how it works).
Am I wrong in that the output to 'have_posts()' should be true on the single.php page? Did I do something wrong with my partials? The banner does use the 'the_title()' tag and 'the_date()' tag but both php tags are properly closed. Would really appreciate some insight on why I am getting false on this. Thanks everyone!
** EDIT ** - When I went to debug the blog-post partial and var_dump the have_posts(), I placed it above the if statement and everything rendered. Looked like so:
<?php
var_dump(have_posts()); // <---------------- Added this and it rendered
if (have_posts()) :
the_post(); ?>
The var_dump output false but then if I did it a second time, it now renders true. Any ideas as to why? For the time being, I am storing a have_posts() in a random variable so there is no output and the post is now showing. While I am happy the post is now showing, I know this isn't necessarily a 'solid fix'. Any ideas with this?
So first I just want to say, #Jeppe you had it right the whole time. If I could mark your comment correct (and if you can, please show me how) I would.
To anyone else who stumbles across this post, it comes down to using the 'rewind_posts()' function. All in all, I have a loop somewhere in my code, that I can't identify as the culprit, that is essentially forcing my 'have_posts()' function to return false because I haven't reset it / rewound it according to WordPress.
My solution was to simply take my old code:
<?php
if (have_posts) :
the_post;
?>
and add the rewind_posts() function above the if statement:
<?php
rewind_posts(); // <---------- This guy right here.
if (have_posts) :
the_post;
?>
This will rewind WordPress's loop and allow have_posts() to print true.
I'm integrating an iframe with dynamic php content in its src on a checkout congratulations page. When the process is complete the iframe with code shows in Firebug, but not on view source in the browser. If I refresh the page the content shows in the browser view source. This, is what I believe, is causing the integration to fail because the iframe is not being picked up by the online service we are using.
Its a Wordpress so the final page calls get_header(); then html/php then get_footer();. Everything in between the header and footer does not show on the view source until I refresh the page, very odd. I tried googling but I found nothing and I'm not sure what even may cause it or where to begin.
Any experience with this?
Edit.
below is the code, everything inside of and including section1 div does not show in view source.
<?php get_header(); ?>
<div class="section1">
<div class="container">
<div class="row">
<div class="col-lg-12 col-md-12 col-sm-12">
<iframe here>
</div>
</div>
</div>
</div>
<?php get_footer(); ?>
Edit:
I still don't know why, but it had to do with destroying all PHP session and browser cookies. Time to mark this one closed. If I ever figure out why,
I'll edit this question.
I'm struggling trying to understand cakephp's views, blocks and layouts.
I need everypage to show a left and right sidebar which content might change. At this moment I have the right sidebar defined in /pages/home.ctp but I'm guessing it would be better to extend that sidebar since it has to appear in everypage. Correct me if that thought is wrong.
Then, I have this view add.ctp for the 'usuarios' table, it practically shows the fields login and password. I want to show this view in the sidebar, but I'm really lost as how to do that.
Thanks in advance.
Lets make this thing easy. Like #patrick said, there is a lots of way.
Start with layout file. Rearrange your default.ctp layout like-
default.ctp layout
<div id="container">
<div id="header">
<?php echo $this->element('header');?>
</div>
<div id="left-sidebar">
<?php echo $this->element('left-sidebar');?>
</div>
<div id="content">
<?php echo $this->Session->flash(); ?>
<?php echo $this->fetch('content'); ?>
</div>
<div id="right-sidebar">
<?php echo $this->element('right-sidebar');?>
</div>
<div id="footer">
<?php echo $this->element('footer');?>
</div>
</div>
Now create elements ctp files as header.ctp, left-sidebar.ctp, right-sidebar.ctp and so on and place them to app/View/Elements.
Your left-sidebar.ctp file may looks like this...
left-sidebar.ctp
// to show login form //
if you just need to show on view.ctp place few logic here for login form.
//end login form//
show other sidebar contents
There are a couple ways to do it, depending on your Cake version. If you're using >=2.1 (which I assume you are since you asked about blocks), then you should try those to see if they work for your setup. The way I usually do things is that if all views for a controller need common markup then those view files would extend a base view within the Controller directory, e.g.
#/View/Posts/index.ctp
<?php
$this->extend('_skel'); //arbitrary filename, I use '_skel' since that makes sense
echo $this->Html->para(null, 'Hello');
#/View/Posts/_skel.ctp
<?php
echo $this->Html->div('sidebar', 'Sidebar for posts...');
echo $this->fetch('content'); // This gets all output from the Posts/index.ctp view
Then all your Posts views which extend _skel will have the sidebar automatically.
Your login module might make sense as an element - something that could be used anywhere in your views.
I have a small problem, and I'll try to break it down into a smaller one so I can explain it properly.
I'm working on a web application and I have a couple of divs, such as this:
<div class="1">
//search bar
</div>
<div class="2">
include_once 'actioncontroller.php';
</div>
<div class="3">
</div>
In the actioncontroller.php I'm having an action controller which decides what action to take depending on what's pressed on the page. I've put it in the second div because ultimately that's where I want to print everything.
My question is, is there any way that I can use the code from the second div in the first one, without it printing it there? Basically I want the search bar from div one to do/print the same thing as the one in div 2 does, but I know(think) that PHP can't see code above the include_once, and if I include the actioncontroller.php in the first div it will print it there, instead of printing it in the second one, as I want.
Hope I was clear enough, it's not a problem of coding, it's just a matter of how can I read the script in the first div and then run it in the second one...
Thanks in advance
My question is, is there any way that I can use the code from the second div in the first one, without it printing it there?
Yes, but the best solution is to change the code you've already written. In the long-term, it is vitally important that you minimize your "procedural" PHP code, so that nothing ever happens simply by include/require-ing a file.
Trust me on this, it works for toy project, but it always leads to insanity and pain in the end. For example, don't put this in a file:
<?php
echo("Header section");
This is bad because you have no choice about when it prints. This is a step up:
<?php
function WriteHeader(){
echo("Header section");
}
Even better would be to use classes an autoloading, but that's probably more than you need to hear right now. With that kind of approach, your main page would look more like:
<?php
// This next line simply makes the class ActionController *available*,
// it does NOT cause new things to happen on its own
include_once("actioncontroller.php");
?>
<div class="1">
<?= ActionController::MakeSomeHTML(); ?>
</div>
<div class="2">
<?= ActionController::MakeSomeHTML(); ?>
</div>
<div class="3">
</div>
This code takes the output of actioncontroller.php and saves it into a variable, which can be echo'd multiple times.
<?php
ob_start();
include_once 'actioncontroller.php';
$output = ob_get_contents();
ob_end_clean();
?>
<div class="1">
<?php echo $output; ?>
</div>
<div class="2">
<?php echo $output; ?>
</div>
I have a web page I am working on in WP which needs some customization.
Firstly I have created a page template that will be used over and over again, only changing parts of the content. I am wondering about available options for me when enabling this fact, through the Admin panel in the HTML Editor(if possible)...
Hope my question is clear enough for you all.
Let me add some code to show what I am trying to accomplish.
<div id="header-style">
<?php get_header();?>
</div>
<div id="content">
<div id="about">
//This is what i want to be able to edit
</div>
<div id="features">
//This is what i want to be able to edit
</div>
</div>
Dino:
There are lots of ways you could do this. The main question I would ask you is, who is going to be adding/editing this content? If you're going to have a community of people adding content, the input needs to be stripped and sanitized (to avoid injecting tags or other harmful content). If its just going to be you, then here's the easiest/fastest solution:
Use custom fields. If you can't see them in the post/page edit screen, go to the little tab on the top right of the post-edit screen that says Screen Options (or something like that) and click "Custom Fields".
Once you can see the Custom Fields edit box, you can add as many fields as you want. These are stored as post meta data. You can use the <?php the_meta(); ?> function in the loop to display all of your custom fields.
You can access a specific field by using get_post_meta(). You pass in the postID and the key of the meta field:
<?php echo get_post_meta(get_the_ID(), 'my_key'); ?>
So, for your example, you would add in the post-edit screen:
about: Some text to go in the about section.
features: Some text to go in the features section.
Then, you would access these on your page like so:
<div id="header-style">
<?php get_header();?>
</div>
<div id="content">
<div id="about">
<?php echo get_post_meta(get_the_ID(), 'about'); ?>
</div>
<div id="features">
<?php echo get_post_meta(get_the_ID(), 'features'); ?>
</div>
</div>
