[英]assign value to an array in smarty php
I am trying to iterate over an array called $module_content
in Smarty/php. 我试图遍历Smarty / php中名为
$module_content
的数组。 When a certain condition is fulfilled, I want to assign a value to this. 当满足特定条件时,我想为此指定一个值。
Dont know why, but my approach does not work. 不知道为什么,但是我的方法行不通。
{php}
global $module_content;
$nopic = "./images/nopic.jpg";
for ($i=0;$i<count($module_content);$i++) {
if ($module_content [$i]['PRODUCTS_IMAGE'] == '') {
$module_content [$i]['PRODUCTS_IMAGE'] = $nopic;
}
else {
if (!file_exists ($module_content [$i]['PRODUCTS_IMAGE']) )
$module_content [$i]['PRODUCTS_IMAGE'] = $nopic;
}
}
{/php}
The Smarty-Template prompts the var PRODUCTS_IMAGE within an iteration. Smarty-Template在一次迭代中提示var PRODUCTS_IMAGE。
{foreach name=aussen item=module_data from=$module_content}
<img src="{$module_data.PRODUCTS_IMAGE}" alt="" />
{/foreach}
Any help appreciated... 任何帮助表示赞赏...
Thank you, in advance. 先感谢您。
{foreach $module_content as $module_data}
{if $module_data.PRODUCTS_IMAGE|file_exist } {* php function file_exist() must be accessible from Smarty*}
<img src="{$module_data.PRODUCTS_IMAGE}" alt="" />
{else}
<img src="./images/nopic.jpg" alt="" />
{/if}
{/foreach}
