如何添加確認消息刪除PHP前 - Moodle的

Question

我有一列像下面。

echo '<td class="icon" align="right"><a title="'.$strdelete.'" href="TL_CORE_viewfile.php?delete='.$re->id.'"><img'. 
      ' src="'.$CFG->pixpath.'/t/delete.gif" class="iconsmall" alt="'.$strdelete.'" /></a></td>'; 

我想刪除之前添加確認消息。我正在使用以下，但有錯誤的行。請任何人都可以幫助我。

echo '<td class="icon" align="right"><a title="'.$strdelete.'" href="TL_CORE_viewfile.php?delete='.$re->id.'" onClick=\"javascript:return confirm('are you sure you want to delete this?');\"><img'. 
      ' src="'.$CFG->pixpath.'/t/delete.gif" class="iconsmall" alt="'.$strdelete.'" /></a></td>'; 

Answer 1

有有斜線的問題。使用下面一行，

echo '<td class="icon" align="right"><a title="'.$strdelete.'" href="TL_CORE_viewfile.php?delete='.$re->id.'" onClick="javascript:return confirm(\'are you sure you want to delete this?\');"><img'. 
      ' src="'.$CFG->pixpath.'/t/delete.gif" class="iconsmall" alt="'.$strdelete.'" /></a></td>';
