如何在刪除PHP前添加確認消息-Moodle

Question

我有一列如下。

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>';

我想在刪除之前添加確認消息。 我正在使用以下內容，但該行有錯誤。 請任何人可以幫助我。

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

斜線有問題。 使用下面的行，

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>';
