我正在尝试添加一个仅对Admin可见的删除按钮。但与此同时,第一行将为用户提供“我已阅读此信息”按钮。在此代码中,无法为所有行隐藏删除按钮。删除按钮仅对第一行隐藏。如果用户不是管理员,我希望删除按钮不会出现在任何地方。
我试过这个javascript代码,但它只影响了我的foreach循环的第一行。我不知道该怎么做。你有什么想法吗?
<?php if(($_SESSION['username'] == 'Admin')) {
echo "<script> $('#del_photo').hide(); </script> ";
}
foreach($select as $index => $rs) {
?>
<div class="post-id" id="<?php echo $rs['id']; ?>" style="margin 300px; overflow: hidden; border-top-right-radius: 25px; border-top-left-radius: 25px; display:block;
position: relative; margin: 20px; border: 2px solid #222;">
<br><br>
<h2 class="blog-post-title"><?php echo $rs['title'];?></h2>
<p class="blog-post-meta"> <?php echo $rs['date'];?> skrevs av <a href="#"> <?php echo $rs['author'];?></a></p>
<?php
$i = 0;
$len = count($select);
foreach ($select as $item) {
if ($i == 0) {
echo "<form action=\"#\" style=\" height:30px; background:transparent; border:none; color:transparent;\" method=\"get\"> <button name=\"readit\" id=\"readit\"
style=\" height:30px; position:absolute; background:transparent; border:none; color:transparent; width:70px; display: flex; top:-0.5%; left:0%; float:right; margin:5px 5px 0 0;\"
class=\"del_photo\"> <span src=\"sett.png\" class=\"readit\" id=\"readit\" ></span><img src=\"sett.png\" class=\"readit\" border=\"0\" /></button> </form>";
} else if ($i == $len - 1) {
echo "// last";
}
$i++;
}
?>
<br>
<center><p style="margin-left:auto; margin-right: auto; display:block; height: 100%; max-width: 100%; margin-bottom:0px;"><?php echo $rs['content'];?></p></center></br>
<img style=" margin-left:auto; margin-right: auto; display:block; height: 100%; max-width: 100%; margin-bottom:0px;" src='<?php echo $rs['image'];?>' width="400" height="300">
<button id="del_photo" style=" background:transparent; border:none; width:350px; height: 250px; color:transparent; display: inline-block;
float:right; margin:5px 5px 0 0; position: absolute; top: 0; right: 0;"
class="del_photo" onclick="deletepost('<?php echo $rs['id']; ?>')"> <span class="del_photo" id="del_photo" src="x.png" style=" display: inline-block;

id="" ></span><img class="del_photo" id="del_photo" src="x.png" style=" display: inline-block;
float:right; margin:5px 5px 0 0; position: absolute; top: 0; right: 0;" class="del_photo" border="0" /></button>
</div>
<?php
}
?>
答案 0 :(得分:1)
问题是你告诉jquery用id="del_photo"
但是id是唯一的,因此在这种情况下不起作用而只隐藏第一个,
所以你最好使用班级del_photo
所以试试
echo "<script> $('.del_photo').hide(); </script> ";
