Drupal 6 PHP：Foreach 不断在同一行上重复操作

发布于 2024-11-19 23:35:04 字数 1349 浏览 1 评论 0原文

我在 Drupal 6 中建立了一个网站，并尝试使用不同的类创建一些跨度以在我的 .tpl (html) 中打印。

在示例中，我在自己的行中列出了两个人。它们都有两个具有不同值的数组，称为“位置”和“首选位置”。

我的问题是，我已经创建了一个 foreach，它打印了跨度，但它每次都在同一行中重复跨度（其中只有两行）。我似乎无法在我的代码中找到错误。请看一下，任何帮助，或者指出正确的方向，我们将不胜感激。

foreach ($vars['view']->result as $key => $row) {
    // preferred positions on pitch             
$outputspanpref = "";           
    foreach ($row->node_data_field_pref_position_field_pref_position_value as $key =>
        $position) {
            $keyclass = 'pref-position-' . $key; 
        $positionclass = strtolower(str_replace(" ","-",$position['value']));
            $outputspanpref .= '<span class="' . $keyclass . ' ' . "pref-position" . 
            '' . $positionclass . '"></span>';      
        $vars['prefposition'] = $outputspanpref;        
    }

    // secondary positions on pitch 

    $outputspan = "";

    foreach ($row->node_data_field_position_field_position_value as $key => 
        $position) {
            $keyclass = 'position-' . $key; 
        $positionclass = strtolower(str_replace(" ","-",$position['value']));
        $outputspan .= '<span class="' . $keyclass . ' ' . $positionclass.'
                </span>';           
        $vars['position'] = $outputspan;        
        }    
    }    
}

I've don a site in Drupal 6, and am trying to make some spans with different classes to print in my .tpl (html).

In the example I have two people listed in their own row. They both have two arrays with different values called 'positions' and 'preferred positions'.

My problem is that I've made a foreach, and it prints the spans, but it keeps repeating the spans each time for the ame row (in this there is only two rows). I can't seem to find the error in my code. Please have a look, any help, or a finger pointed in the right direction would be appreciated.

foreach ($vars['view']->result as $key => $row) {
    // preferred positions on pitch             
$outputspanpref = "";           
    foreach ($row->node_data_field_pref_position_field_pref_position_value as $key =>
        $position) {
            $keyclass = 'pref-position-' . $key; 
        $positionclass = strtolower(str_replace(" ","-",$position['value']));
            $outputspanpref .= '<span class="' . $keyclass . ' ' . "pref-position" . 
            '' . $positionclass . '"></span>';      
        $vars['prefposition'] = $outputspanpref;        
    }

    // secondary positions on pitch 

    $outputspan = "";

    foreach ($row->node_data_field_position_field_position_value as $key => 
        $position) {
            $keyclass = 'position-' . $key; 
        $positionclass = strtolower(str_replace(" ","-",$position['value']));
        $outputspan .= '<span class="' . $keyclass . ' ' . $positionclass.'
                </span>';           
        $vars['position'] = $outputspan;        
        }    
    }    
}

看起来您正在嵌套的 foreach 循环中重复使用 $key 。尝试在每个后续循环中使用 $key1，然后使用 $key2 等。

foreach ($vars['view']->result as $key1 => $row) { // 1st forloop
foreach ($row->node_data_field_pref_position_field_pref_position_value as $key2 => $position) { // 2nd forloop
foreach ($row->node_data_field_position_field_position_value as $key3 => $position) { // 3rd forloop

It looks like you're re-using $key within nested foreach loops. Try using $key1, then $key2, etc for each subsequent loop.

foreach ($vars['view']->result as $key1 => $row) { // 1st forloop
foreach ($row->node_data_field_pref_position_field_pref_position_value as $key2 => $position) { // 2nd forloop
foreach ($row->node_data_field_position_field_position_value as $key3 => $position) { // 3rd forloop
