Question

我正在尝试在我的视图页面上找出我的复选框错误解析错误：语法错误，意外'如果'（T_IF）

我不确定该错误是什么以及如何修复它。

foreach ($user->result() as $row) {

echo '<tbody>';
echo '<tr>';
echo '<td class="text-center">' . if (in_array($row->user_id, $selected)) {  .'</td>';
echo '<td class="text-center">' . form_checkbox(array('name' => 'selected[]', 'value' => $row->user_id, 'checked' => 'checked')) .'</td>';
echo } else {;
echo '<td class="text-center">' . form_checkbox(array('name' => 'selected[]', 'value' => $row->user_id)) .'</td>';
echo };
echo '<td class="text-center">' . $row->user_id  .'</td>';
echo '<td class="text-center" style="font-weight: bolder;">' . $row->username  .'</td>';
echo '<td class="text-center">' . ($row->status ? $this->lang->line('text_enabled') : $this->lang->line('text_disabled'))  .'</td>';
echo '<td class="text-center">' . $row->date_added  .'</td>';
echo '<td class="text-center">' . anchor("admin/users/edit/" . $row->user_id, '<div class="btn btn-primary text-right" role="button"><i class="fa fa-pencil"></i>
 Edit</div>')  .'</td>';
echo '</tr>';
echo '</tbody>';

}

Answer 1

由于你在串联中使用if()，你需要重构：

foreach ($user->result() as $row) 
{
    echo '<tbody>';
        echo '<tr>';

        if (in_array($row->user_id, $selected)) 
        {
            echo '<td class="text-center">' . form_checkbox(array('name' => 'selected[]', 'value' => $row->user_id, 'checked' => 'checked')) .'</td>';
        }
        else
        {
            echo '<td class="text-center">' . form_checkbox(array('name' => 'selected[]', 'value' => $row->user_id)) .'</td>';
        }

        echo '<td class="text-center">' . $row->user_id  .'</td>';
        echo '<td class="text-center" style="font-weight: bolder;">' . $row->username  .'</td>';
        echo '<td class="text-center">' . ($row->status ? $this->lang->line('text_enabled') : $this->lang->line('text_disabled'))  .'</td>';
        echo '<td class="text-center">' . $row->date_added  .'</td>';
        echo '<td class="text-center">' . anchor("admin/users/edit/" . $row->user_id, '<div class="btn btn-primary text-right" role="button"><i class="fa fa-pencil"></i> Edit</div>')  .'</td>';
        echo '</tr>';
    echo '</tbody>';
}

或多或少你应该更好地遵循这种方法。你不能连接echo / print中的if语句。

foreach ($user->result() as $row) {
$out = '<tbody>';
$out .= '<tr>';
$out .= '<td class="text-center">';
$out .='</td>';
if (in_array($row->user_id, $selected)) {      
  $out .= '<td class="text-center">' . form_checkbox(array('name' => 'selected[]', 'value' => $row->user_id, 'checked' => 'checked')) .'</td>';
} 
else {
  $out .= '<td class="text-center">' . form_checkbox(array('name' => 'selected[]', 'value' => $row->user_id)) .'</td>';
}
$out .= '<td class="text-center">' . $row->user_id  .'</td>';
$out .= '<td class="text-center" style="font-weight: bolder;">' . $row->username  .'</td>';
$out .= '<td class="text-center">' . ($row->status ? $this->lang->line('text_enabled') : $this->lang->line('text_disabled'))  .'</td>';
$out .= '<td class="text-center">' . $row->date_added  .'</td>';
$out .= '<td class="text-center">' . anchor("admin/users/edit/" . $row->user_id, '<div class="btn btn-primary text-right" role="button"><i class="fa fa-pencil"></i>
 Edit</div>')  .'</td>';
$out .= '</tr>';
$out .= '</tbody>';
}

echo $out;
