 Posted: Tue Jan 05, 2021 5:54 pm Post subject: [gelöst] funciton hmtl_image -> max height/width |
 |
|
Nabend Leute...
So ich hab mich nun durch google und durch viele viele englishe Postings hier gearbeitet, aber irgendwie geht das alles nicht... vllt kann mir wer das mal in Deutsch vermitteln hier:
ich lade aus ner DB nen Array mit u.A. Adressen zu img-files ... das funzt auch. Nun haben die aber blöderweise alle unterschiedliche Größen.
Jetz versuche ich seit geraumer Zeit hier die function.html_image.php dementsprechend nach Googlefunden umzuändern, dass ich maxheight bzw maxwidth im img-tag angeben kann.
übrigens baut sich mein img-tag wie folgt auf:
| Code: | | {html_image file="{$row.3}" title="{$row.1}" alt="{$row.1}"} |
Jetzt hab ich zwar auch zig function.html_image.php im www via google gefunden, aber kaum änder ich die auf meinem Server zersetzt es mir die 'partner.php', in der unter anderem o.g. tag zu finden ist...
| Code: |
<?php
/**
* Smarty plugin
* @package Smarty
* @subpackage plugins
*/
/**
* Smarty {html_image} function plugin
*
* Type: function<br>
* Name: html_image<br>
* Date: Feb 24, 2003<br>
* Purpose: format HTML tags for the image<br>
* Input:<br>
* - file = file (and path) of image (required)
* - height = image height (optional, default actual height)
* - width = image width (optional, default actual width)
* - basedir = base directory for absolute paths, default
* is environment variable DOCUMENT_ROOT
* - path_prefix = prefix for path output (optional, default empty)
*
* Examples: {html_image file="/images/masthead.gif"}
* Output: <img src="/images/masthead.gif" width=400 height=23>
* @link http://smarty.php.net/manual/en/language.function.html.image.php {html_image}
* (Smarty online manual)
* @author Monte Ohrt <monte at ohrt dot com>
* @author credits to Duda <duda@big.hu> - wrote first image function
* in repository, helped with lots of functionality
* @version 1.0
* @param array
* @param Smarty

für function.html_image.php zum Beispiel legt mir wie gesagt die Seite lahm.

Übrigens wird von mir Smarty 3.1.34-dev-7 verwendet....
