Ignore image tages in body
Hey,
for a mobile version of a website I’d like to ignore the image tags which are placed in the body field. Are there any possibilities to do this?
Thanks in advance,
David

Re: Ignore image tages in body
What about hiding them (display:none;) via CSS, by having a specific rule?
body.is_mobile div.article_body img {
display:none;
}
Not sure if this will prevent downloading at all. That may depend on many different factors.
Alternatively, you may want to try smd_macro, to create a macro to embed images in the body field. Then, inside the macro, you use some kind of logic (via adi_mobile, for example), to decide if you want to output the image or not.

Hi maniqui,

I tried that, but that won’t prevent loading the images.
The smd_macro idea seems to be a possibility, maybe i’ll give it a try (but then I’ll have to work on upm_image_popper which I use for embedding images :-)

Unless you use JavaScript, or CSS background property instead of HTML img tags, no it won’t.

You could potentially use a form to output images. E.g.
<txp:output_form form="img">11</txp:output_form>
And then in the img form:
<txp:adi_if_mobile>
<!--
A mobile browser, do something else
-->
<txp:else />
<txp:images id='<txp:yield />'>
<txp:thumbnail />
</txp:images>
</txp:adi_if_mobile>
But that would require that you use the specific snippet to add every single image. No Textile or anything else allowed. Other, more robust, better solution might actually be some post-precessing. Like stripping the images with some regular expressions. I.e.
<txp:php>
echo preg_replace('/<img[^>]+\>/i', '', body());
</txp:php>
Above would print out <txp:body /> with all <img/> instances removed. That could be then used with adi_mobile. E.g.
<txp:adi_if_mobile>
<txp:php>
echo preg_replace('/<img[^>]+\>/i', '', body());
</txp:php>
<txp:else />
<txp:body />
</txp:adi_if_mobile>

Gocom, made my day. That’s it – and so easy. Thank you very much!
