php - 页面未从 mysql 中的表中引入正确的行

Question

我似乎对这行代码有问题，它应该通过浏览器地址栏中的引用字段引入。

echo <a href="update.php?Reference=<? echo $rows['Reference']; ?>">update</a>

它在地址栏中应该看起来像这样“localip/update.php?Reference=123456”

而是这样的“localip/update.php?Reference=”

它似乎没有通过该字段进入地址栏来显示表中该行的信息。

任何帮助将不胜感激(这对所有这一切来说都是新的)

干杯

尝试这样的事情

echo "<a href='update.php?Reference='". $rows['Reference']."'>update</a>";
