        Assign Task to Every User? &nbsp; &nbsp; 
        <input type="checkbox" name="display_insert_email" onchange="this.form['email'].hidden=this.checked" />
    </li>
    <li>
        <input type="text" name="email" style="width: 400px;" value="<?php if ($task_member_id > 0){ echo $task_member_email; } else 'Please enter email address of user'?>" onclick="if(this.value=='Please enter email address of user'){this.value=''}" onblur="if(this.value==''){this.value='Please enter email address of user'}" >
    </li>

这是两个有问题的区域，如果$project_member_id = 0我希望复选框的值被选中..

我已经搜索和搜索，但我找不到与我相关的任何内容，我可能正在搜索错误的内容，但任何帮助将不胜感激！
