如何在 php 中删除前添加确认消息 - moodle

Question

我有一个像下面这样的专栏。

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>';

我想在删除前添加确认消息。我正在使用以下但该行有错误。请任何人帮助我。

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

斜杠有问题。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>';
