我试图用复选框表单提交多个数组,但我现在只能提交一个数组,这里是我到目前为止
在这个例子中,我使用delete []数组提交一个数组数组,这个数组得到正确的处理,我也想提交数组条件[]这个没有得到正确的处理,最好的方法是解决这个问题？
$catalog = $database->getInventory();
if($catalog){
$numRows = sizeof($catalog);//count
echo "<b>Book Count:</b> ".$numRows."<br>";
echo "<form method='post' action='inventory.PHP'>";
echo "<table id='example' class='tablesorter' border='0' cellpadding='0' cellspacing='1'>";
echo "
<thead>
<tr>
<th>ISBN</th>
<th>Title </th>
<th>Rank </th>
<th>Condition </th>
<th><input type='checkBox' name='delete' value='all' /></th>
</tr>
</thead>\n";
foreach($catalog as $elem){
echo "
<tr>
<td>".$elem["isbn"]."</td>
<td>".$elem["title"]."</td>
<td>".$elem["rank"]."</td>
<td>".$elem["condition"]."</td>
<td>
<input type='checkBox' name='add[]'
value='".$elem['isbn']."_".$elem['condition']."_"."' />
</td>
</tr>";
}
echo "</table>";
echo "</form>";
}
示例html标记
<form method='post' action='inventory.PHP'> <table> <tr> <td> <input type='hidden' name='addInventoryBook' value='1'> <input type='submit' value='Add' /> </td> </tr> <tr> <td> <input type='checkBox' name='add[]' value='100001_used' /> </td> </tr> <tr> <td> <input type='checkBox' name='add[]' value='100001_new' /> </td> </tr> <tr> <td> <input type='checkBox' name='add[]' value='100003_new' /> </td> </tr> </table> </form>
function Inventory(){
if(isset($_POST['addInventoryBook'])){
if(isset($_POST['add']) && is_array($_POST['add'])){
$arr = array();
foreach($_POST['add'] as $checkBox){
$temp = explode("_",$checkBox);
$arr[] = array(
"isbn" => $temp[0],"condition" => $temp[1],"sub_condition" => $temp[2]
);
}
$this->addInventoryBook($arr);
}
else{
echo "No values have been set";
}
}
function addInventoryBook($arr){
foreach($arr as $elem){
//if used get sub-category
if($elem['condition']=='used'){
echo $elem['isbn']."-".ucfirst($elem['condition'])
.ucfirst($elem['sub_condition'])."<br>";
}
else if($elem['condition']=='new'){
echo $elem['isbn']."-".ucfirst($elem['condition'])."<br>";
}
}
}
所有我想要的是基本上能够通过两个数组到我的PHP脚本
当前输出
100001 100002 100003
所需输出
100001 good 100002 new 100003 new
我怀疑的问题是,只有被勾选的复选框将被传回服务器,而所有隐藏的字段将始终被传递,这样数组的长度将会不同,并且密钥不会对应.
对此的解决方案实际上比较简单 – 您只需要指定条件数组的键,以便可以再次匹配值.这样的东西
HTML：
<tr>
<td>
<input type='hidden' name='condition[100001]' value='good' />
<input type='checkBox' name='delete[]' value='100001' />
</td>
</tr>
<tr>
<td>
<input type='hidden' name='condition[100002]' value='new' />
<input type='checkBox' name='delete[]' value='100002' />
</td>
</tr>
PHP：
foreach ($_POST['delete'] as $delete) {
$condition = $_POST['condition'][$delete];
// Do stuff
}
这将$_POST [‘condition’]数组中的值与$_POST [‘delete’]数组备份起来,所以一切都会再次匹配.
编辑
上面创建密钥的方式并不好,回想起来,这样做是错误的.
为了演示正确的方法,让我们想象一下,我们有以下数组,不错,简单：
$books = array( 10001 => 'good',10002 => 'new',10003 => 'new',10004 => 'good' );
我们需要做的是捆绑与每本书相关联的两个输入,这意味着我们需要一组可以匹配的键/值对.这听起来像是一个阵列给我.但与上面的示例不同,这些键应该与数据无关 – 它们不需要任何意义,因为我们所需要的就是数据.
我们需要做的是明确指定每个单个键(没有堆栈式数组推),并使密钥与其相关的数据不可知.
我们做得到：
$i = 0;
foreach ($books as $isbn => $condition) {
echo "
<tr>
<td>
<input type='hidden' name='condition[$i]' value='$condition' />
<input type='checkBox' name='delete[$i]' value='$isbn' />
</td>
</tr>
";
$i++;
}
…然后,当提交表单时,我们可以这样做：
// We still base our code on $_POST['delete'] - because this is the array that
// depends on the user input. This time,though,we'll look at the keys as well
foreach ($_POST['delete'] as $key => $isbn) {
$condition = $_POST['condition'][$key];
// Do stuff
}
