Question

嘿我目前遇到的问题是尝试使我的输入按钮具有我需要的id /服务器的值，它显示不同的值这是我的代码当前的样子我知道HTML和表单无效我将重构它，但是我正在尝试获取服务器标识符和id标识符以交叉到另一个页面

<?php
$propertyType = $xmlDom1->getElementsByTagName('PropertyType');
$rent = $xmlDom1->getElementsByTagName('rates');
$rooms = $xmlDom1->getElementsByTagName('rooms');
//$server = $xmlDom1->getElementsByTagName('server');
$propertyServer = $xmlDom1->getElementsByTagName('Property');
$propertyID = $xmlDom1->getElementsByTagName('Property');
$imageURL = $xmlDom1->getElementsByTagName('url');
$imageAlt = $xmlDom1->getElementsByTagName('altText');
$server = $propertyID->item($i)->getAttribute('server');
echo '<form action="level5Details.php" method="get" enctype="application/x-www-form-urlencoded">';
echo '<table><th>Type:</th><th>Rent:</th><th>Rooms:</th><th>Server</th>';
$records = $xmlDom1->documentElement->childNodes;
for ($i = 0; $i < $records->length; $i++) {
    echo "<tr><td>".$propertyType->item($i)->nodeValue."</td>";
    echo "<td>".$rent->item($i)->nodeValue."</td>";
    echo "<td>".$rooms->item($i)->nodeValue."</td>";
    echo "<td>".$propertyServer->item($i)->getAttribute('Server')."</td>"; 
    echo '<td><img src="data:image/jpeg;base64,'.$imageURL->item($i)->nodeValue.'" alt="'.$imageAlt->item($i)->nodeValue.'"></img></td>';
?> 
    <td>
        <button class="submit" type="submit" value="<?php echo $propertyID->item($i)->getAttribute('pid');  ?>" name="submit22">something </button>
    </td>
 </tr>
<?php 
} 
?>
</form>

如果您尝试使用一个按钮生成大量表单，那么您需要将表单放在像这样的表格单元格中

将要传递的数据项放在隐藏字段中而不是尝试将2个数据项放在按钮值中可能也很有用

<?php
$propertyType = $xmlDom1->getElementsByTagName('PropertyType');
$rent = $xmlDom1->getElementsByTagName('rates');
$rooms = $xmlDom1->getElementsByTagName('rooms');
//$server = $xmlDom1->getElementsByTagName('server');
$propertyServer = $xmlDom1->getElementsByTagName('Property');
$propertyID = $xmlDom1->getElementsByTagName('Property');
$imageURL = $xmlDom1->getElementsByTagName('url');
$imageAlt = $xmlDom1->getElementsByTagName('altText');
$server = $propertyID->item($i)->getAttribute('server');
echo '<table><th>Type:</th><th>Rent:</th><th>Rooms:</th><th>Server</th>';
$records = $xmlDom1->documentElement->childNodes;
for ($i = 0; $i < $records->length; $i++) {
    echo "<tr><td>".$propertyType->item($i)->nodeValue."</td>";
    echo "<td>".$rent->item($i)->nodeValue."</td>";
    echo "<td>".$rooms->item($i)->nodeValue."</td>";
    echo "<td>".$propertyServer->item($i)->getAttribute('Server')."</td>"; 
    echo '<td><img src="data:image/jpeg;base64,'.$imageURL->item($i)->nodeValue.'" alt="'.$imageAlt->item($i)->nodeValue.'"></img></td>';

    $pid = $propertyID->item($i)->getAttribute('pid'); 
?> 
    <td>
        <form action="level5Details.php" method="get" enctype="application/x-www-form-urlencoded">
            <input type="hidden" name="pid" value="<?php echo $pid;?>">
            <input type="hidden" name="server" value="<?php echo $server;?>">
            <button class="submit" type="submit" value="submit" name="submit22">something</button>
        </form>
    </td>
    </tr>
<?php 
} 
?>

如果您只是希望按钮携带所有数据并且只有一个表单，则必须将2个数据项打包成一个字符串并将其作为按钮的值发送

<?php
$propertyType = $xmlDom1->getElementsByTagName('PropertyType');
$rent = $xmlDom1->getElementsByTagName('rates');
$rooms = $xmlDom1->getElementsByTagName('rooms');
//$server = $xmlDom1->getElementsByTagName('server');
$propertyServer = $xmlDom1->getElementsByTagName('Property');
$propertyID = $xmlDom1->getElementsByTagName('Property');
$imageURL = $xmlDom1->getElementsByTagName('url');
$imageAlt = $xmlDom1->getElementsByTagName('altText');
$server = $propertyID->item($i)->getAttribute('server');

echo '<form action="level5Details.php" method="get" enctype="application/x-www-form-urlencoded">';

echo '<table><th>Type:</th><th>Rent:</th><th>Rooms:</th><th>Server</th>';
$records = $xmlDom1->documentElement->childNodes;

for ($i = 0; $i < $records->length; $i++) {
    echo "<tr><td>".$propertyType->item($i)->nodeValue."</td>";
    echo "<td>".$rent->item($i)->nodeValue."</td>";
    echo "<td>".$rooms->item($i)->nodeValue."</td>";
    echo "<td>".$propertyServer->item($i)->getAttribute('Server')."</td>"; 
    echo '<td><img src="data:image/jpeg;base64,'.$imageURL->item($i)->nodeValue.'" alt="'.$imageAlt->item($i)->nodeValue.'"></img></td>';

    $dataPackage = $propertyID->item($i)->getAttribute('pid') . ':' . $server; 
?> 
    <td>
        <button class="submit" type="submit" value="<?php echo $dataPackage;?>" name="submit22">something</button>

    </td>
    </tr>
<?php 
} 
</table>
</form>
?>

现在在接收表单中解压缩数据以供使用

<?php
// usual checks for things existing
list($pid, $server) = explode(':', $_GET['submit22'];

PHP按钮单击 - 值/ id传递
