截至目前,当我单击“提交”按钮时,文本框中未显示任何内容。我正在提交id
,以便该程序知道要查找的字段。

我的提交和输入类型名称id
<form action="" method="POST">
<div class="row col-md-4">
<label>Code</label>
<input type="text" name="id" class="form-control validate" id="mapo">
<br>
<input type="submit" class="form-control btn-warning" name="search" value="Search Data"></input><br>
在phpmyadmin数据库中连接我的php:
$connection = mysqli_connect("localhost","root","");
$db = mysqli_select_db($connection, 'qrproject');
这是单击按钮时我的isset语句,然后将弹出文本框
if(isset($_POST['search']))
{
$id = $_POST['id'];
$query = "SELECT * FROM scratch_cards WHERE id='$id' ";
$query_run = mysqli_query($connection, $query);
while($row = mysqli_fetch_array($query_run))
{
?>
<form action="" method="POST">
<input type="hidden" name="id" value="<?php $row['id'] ?>" class="form-control validate">
<label>PIN</label>
<input type="text" name="pin" value="<?php $row['pin'] ?>" class="form-control validate" id="mact">
<br>
<label>Price</label>
<input type="number" name="amount" value="<?php $row['amount'] ?>" class="validate form-control" id="soluong">
<br>
<label>Card Expiration</label>
<input type="date" name="card_expiration" value="<?php $row['card_expiration'] ?>" class="validate form-control" id="cardex">
<br>
<label>Card Validity</label>
<input type="text" name="card_validity" value="<?php $row['card_validity'] ?>" class="validate form-control" id="cardval">
<br>
<label>Status</label>
<input type="text" name="status" value="<?php $row['status'] ?>" class="validate form-control" id="stats">
<br>
</form>
<?php
}
}
?>
</form>
答案 0 :(得分:2)
第二个文件中的所有代码都没有打印命令。
更改自
<input type="hidden" name="id" value="<?php $row['id'] ?>" class="form-control validate">
到
<input type="hidden" name="id" value="<?php echo $row['id'] ?>" class="form-control validate">
对每个输入都执行此操作,一切都会正常工作。
