Question

如果有人可以帮助我，我在修复了很多其他错误后遇到了这个错误。

700号线

<input id="refer" placeholder="<?php echo $txt['not_oblige']; ?>" type="text" name="referer" value="<?php echo $_GET['referer']; ?>" class="form-control" />

错误

未定义的索引：第700行的C：\ wamp \ www \ PTT \ login.php中的referer调用堆栈#TimeMemoryFunctionLocation 10.0010416272 {main}（）.. \ login.php：0＆＃34;类=＆＃34;形状控制＆＃34; /＆GT;

PHP无法在变量$ _GET中找到索引引用程序，您应首先测试索引是否存在，试试这个：

<强> PHP

<input id="refer" placeholder="<?php echo $txt['not_oblige']; ?>" type="text" name="referer" value="<?php echo (isset($_GET['referer'])) ? $_GET['referer'] : '' ; ?>" class="form-control" />
