1) Easy Way - New Custom BBCode Through Admin Control Panel (ACP)
You can add a custom BBCode Tag in your ACP. Follow the steps as below
a) Go to ACP -> Posting -> BBCodes -> Add a new BBCode.
b) In BBCode usage, type
- Code: Select all
[rimg width={NUMBER1} height={NUMBER2}]{URL}[/rimg]
- Code: Select all
[rimg=({NUMBER1},{NUMBER2}]{URL}[/rimg]
c) In HTML replacement, type
- Code: Select all
<img src='{URL}' width='{NUMBER1}' height='{NUMBER2}' />
d) Type whatever you want in Help Line.
e) If needed Enable "Display on Posting Page" option and give submit.
However, I feel that above method has two disadvantages. One is, we need to have a separate BBCode for resizing alone, which the users may feel uncomfortable. Another reason is that, I can't make width/height optional. So I would need to have different BBCodes for different combinations like {width present, height absent} or {width absent, height present} etc. This makes things more complicated.
Because of these, I tried to find a mod that will make necessary changes so that I could use the same [ img ] BBCode, But still use width and height, and that too optionally. But google search didn't give me positive results. There wasn't much information about this. (Found one alternative though)
So here is my method to edit the BBCode files to make this work. This is my first attempt to make a modification in PHPBB3, so I would like someone to tell how good it is.
2) Edit BBCodes files directly (CAUTION : Take necessary backups of files you are editing, as it may screw up things, if anything went wrong).
Thanks to this thread which was like a starter for me to attempt this modification. I edited a template based on Pro Silver.
a) Open <Forum Root Folder>\styles\<Template Name>\template\template.cfg
Find
- Code: Select all
template_bitfield = lNg=
Replace
- Code: Select all
template_bitfield = nNg=
(Reason could be found here)
b) Install the style. (If you have already installed this template, even if you uninstall and install the template this mod won't work. Because, the above replacement is not reflected in the Database while reinstalling the template. If you have already installed this template, go to your sql db manager, open the table TABLE-PREFIX_styles_template, browse and edit "bbcode_bitfield" field corresponding to the template you are editing. )
c) Open <Forum Root Folder>\styles\<Template Name>\template\bbcode.html
Find
- Code: Select all
<!-- BEGIN img --><img src="{URL}" alt="{L_IMAGE}" /><!-- END img -->
After that ADD this
- Code: Select all
<!-- BEGIN imgw --><img src="{URL}" width="{WIDTH}" alt="{L_IMAGE}" /><!-- END imgw -->
<!-- BEGIN imgh --><img src="{URL}" height="{HEIGHT}" alt="{L_IMAGE}" /><!-- END imgh -->
<!-- BEGIN imgwh --><img src="{URL}" width="{WIDTH}" height="{HEIGHT}" alt="{L_IMAGE}" /><!-- END imgwh -->
d) Open <Forum Root Folder>\includes\message_parser.php
Find
- Code: Select all
'img' => array('bbcode_id' => 4, 'regexp' => array('#\[img\](.*)\[/img\]#iUe' => "\$this->bbcode_img('\$1')")),
Replace with
- Code: Select all
'img' => array('bbcode_id' => 4, 'regexp' => array('#\[img( width=([0-9]+))?( height=([0-9]+))?\](.*)\[/img\]#iUe' => "\$this->bbcode_img('\$2','\$4','\$5')")),
