Insert an specific iframe

[manudevil]

Hello !

I wanted to know if such a plugin exist. I want to insert an iframe in a post. A friend of mine has developped a kind of calendar, and I need to insert his calendar in a post, using a pseudo code. Do you know if such a mod exist ?

Thank you in advance.

If you are admin, and if you definitely trust the source you are loading it from, you can just use HTML BBC and any html-code inside a post.

You as the admin can do so using the [html] bbcode, just use that bbcode and put your iframe in it.

Non admins will not be able to use the html bbcode for security reasons.

[manudevil]

Oh, good idea ! But I need it simpler, just with a pseudo code, if possible.
If you know a plugin that could do quite the same, I could use it like an inspiration, and modify it for my specific needs.

There are many BBCode mods available that embed content into posts. Any of them could be used as inspiration.

Also, it is strongly recommended that you build your mod to use only integration hooks even if it is only for your own private use, so it would be best to take your inspiration from mods that are labelled as "Hooks Only" on the Customization site.

I do have to ask why it needs to be "simpler".

I'm not even sure it actually *can* be meaningfully simpler. An iframe is one tag, it has its dimensions, it might have a few other things but it's still one line of code, put inside one bbcode.

Unless you're putting this in lots of posts, or you want to let other people post it in their posts, I'm honestly not sure it's worth the effort to wrap it in a "simple" bbcode.

I need to insert the day of the calendar on the post of the day. Two posts by weeks, so... And not only the admin could do that.
I need to do that : https://forum.crazy-orc.org/index.php/board,3.0.html but for SMF 2.1.x

[Arantor]

And is the iframe code itself different every time?

[manudevil]

Slightly, we pass the date as parameter.

[Arantor]

So you've got to change it every time anyway... in the same way whether using a bbcode or not. Still might as well save the effort and just use what comes out of the box.

Or use the custom bbcode mod, should be able to do that but... you do already have all the tools you need and the saving isn't as great as might be imagined.

[manudevil]

Custom BBcode seems to be a great solution. I'll give it a try.
Thank you, you are very helpful.

[manudevil]

Alright. Custom BBcode didn't make the trick. So I developed my own plugin. But it is a little tricky for some details, I guess I need help. Is it here, or must I begin another topic ?

Thank you.

[Arantor]

Here's fine, what exactly do you need?

[manudevil]

I'm using the hook system to add a bbcode: [planificatorc]YYYY-MM-DD[/planificatorc]
Inside, there is obviously a date.
The mod changes the bbcode for an iframe, passing the date in parameter. In the iframe, there is a windows displaying informations on a specific calendar. And there is a Javascript script which allows the iframe to be the exact height of its content.
For that, I need a JS in the iframe, and a JS in the forum. It works well.
But...
How is it possible to load a JS script just once? If I load it on the function, it loads everytime we are using the bbcode...

Here is my PHP code:

<?php

/**

 if (!defined('SMF')) {
  die('No direct access...');
 }

/**

function planificatorc_bbc(&$codes, &$no_autolink_tags)
{
  loadJavaScriptFile('iframeResizer.min.js');
  $url = "https://forum.crazy-orc.org/planificatorc/PlanningJour.php?date=$1";
  $iframe = '<iframe src="'.$url.'" frameborder="0" marginheight="1" marginwidth="1" style="width: 100%; height: 450px;"></iframe>';
  $content = <<<HEREDOC
$iframe
<script>
/* http://davidjbradshaw.github.io/iframe-resizer/ */
var iframes = iFrameResize({
checkOrigin: false,
enablePublicMethods: true
});
</script>
HEREDOC;

  $codes[] = array(
    'tag' => 'planificatorc',
    'type' => 'unparsed_content',
    'content' => $content,
    'block_level' => true,
  );
}

Thanks in advance!

First line of the function should be:

static $loaded = false;

Then you can check if you have been loaded already:

if(!$loaded) {
  // call loadJavaScriptFile or whatever else is one time only
  $loaded = true
}

Making $loaded static means its value will be kept after each run so the first time, it gets set up to be false, checked that it is false, then you call loadJavaScriptFile (I'm on iPad, anything code is annoying!) then set $loaded to true, next time the function is called on that page, $loaded will still be true so won't trigger again.

[manudevil]

So simple and elegant.
Thank you, I soulda think of that myself. Brilliant!
