提交单击的当前行中隐藏输入的一个值

Question

如何在PHP中传递多个隐藏输入的当前行的一个值。我有以下代码：

foreach($portfolio as $portfolio){
echo  "<tr class ='table-comments'>";
echo  "<td>".$portfolio['portfolio_title']."</td>";
echo  "<td class = 'comment-content'>".$portfolio['portfolio_client']."</td>";
echo  "<td><a target = '_blank' href = ".$portfolio['portfolio_link'].">".$portfolio['portfolio_link']."</a></td>";
echo  "<td>";
echo  "<input type='hidden' name='portfolio_id' value='" . $portfolio['portfolio_id'] . "' />";
echo "<input type = 'submit'  value = 'Edit'>";
echo "<input type = 'submit' value = 'Move to Trash' class = 'action-button'>";
echo  "</td>";
echo  "</tr>";
}

我在触发表单的每一行都有提交按钮。当我单击提交按钮时，它会提交隐藏输入行的所有值。我只想要单击的按钮行值。

URL是这样的：

/portfolio?portfolio_id=1&portfolio_id=2&portfolio_id=3&portfolio_id=4等

我只想要

/portfolio?portfolio_id=3

Answer 1

为每行创建一个新表单。。。

<form method="get">
</form>

像这样：

foreach($portfolio as $portfolio){
echo  "<tr class ='table-comments'>";
echo  "<td>".$portfolio['portfolio_title']."</td>";
echo  "<td class = 'comment-content'>".$portfolio['portfolio_client']."</td>";
echo  "<td><a target = '_blank' href = ".$portfolio['portfolio_link'].">".$portfolio['portfolio_link']."</a></td>";
echo  "<td>";
echo '<form method="get">';
echo  "<input type='hidden' name='portfolio_id' value='" . $portfolio['portfolio_id'] . "' />";
echo "<input type = 'submit'  value = 'Edit'>";
echo "<input type = 'submit' value = 'Move to Trash' class = 'action-button'>";
echo "</form>";
echo  "</td>";
echo  "</tr>";
}

Answer 2

如果您提交的只是那个ID，并且您使用的是GET而不是POST，那么您甚至可以不使用表单，而是使用链接。如果您愿意，您仍然可以将链接样式设置为按钮，但使用链接在语义上会更有意义。删除隐藏的输入，并让每个链接都有您想要的URL。

循环中应该包含form标记。

更改此

foreach ($portfolio as $portfolio) {
echo  "<tr class ='table-comments'>";
echo  "<td>".$portfolio['portfolio_title']."</td>";
echo  "<td class = 'comment-content'>".$portfolio['portfolio_client']."</td>";
echo  "<td><a target = '_blank' href = ".$portfolio['portfolio_link'].">".$portfolio['portfolio_link']."</a></td>";
echo  "<td>";
echo  "<input type='hidden' name='portfolio_id' value='" . $portfolio['portfolio_id'] . "' />";
echo "<input type = 'submit'  value = 'Edit'>";
echo "<input type = 'submit' value = 'Move to Trash' class = 'action-button'>";
echo  "</td>";
echo  "</tr>";
}

至：

foreach ($portfolio as $portfolio) {
echo  "<tr class ='table-comments'>";
echo  "<td>".$portfolio['portfolio_title']."</td>";
echo  "<td class = 'comment-content'>".$portfolio['portfolio_client']."</td>";
echo  "<td><a target = '_blank' href = ".$portfolio['portfolio_link'].">".$portfolio['portfolio_link']."</a></td>";
echo  "<td>";
echo  "<form action='process.php' method='get'>";
echo  "<input type='hidden' name='portfolio_id' value='" . $portfolio['portfolio_id'] . "' />";
echo "<input type = 'submit'  value = 'Edit'>";
echo "<input type = 'submit' value = 'Move to Trash' class = 'action-button'>";
echo "</form>";
echo  "</td>";
echo  "</tr>";
}
