我正在尝试按另一个数组对一个数组进行排序。这两个数组都从表单中获取内容。
这是我的表单代码:
<form method="post" action="">
<div class="groupcontainer">
<br/><label>Group One:</label><br/>
<input type="text" name="groupname[]" value="groupone" /><br/>
<br/><label>Variable Group One:</label><br/>
<input type="text" name="variable[]" value="variableone" />
<input type="text" name="variable[]" value="variabletwo" />
</div>
<br/>
<div class="groupcontainer">
<br/><label>Group Two:</label><br/>
<input type="text" name="groupname[]" value="grouptwo" /><br/>
<br/><label>Variable Group Two:</label><br/>
<input type="text" name="variable[]" value="variablethree" />
<input type="text" name="variable[]" value="variablefour" />
</div>
<br/>
<input type="submit" name="submit" value="Submit" />
</form>
以下是PHP代码:
<?php
if (!$_POST['submit'] == "") {
foreach($_POST['groupname'] as $groupname) {
$groupnum = 1;
foreach($_POST['variable'] as $variable) {
print "$".$groupname.$groupnum." = '".$variable."';<br/>";
$groupnum++;
}
print "$".$groupname." = array(";
for ($arrnum = 1; $arrnum <= count($_POST['variable']); $arrnum++) {
print "$".$groupname.$arrnum.", ";
}
print ");<br/><br/>";
}
}
?>
这是我提交表单时得到的结果:
$groupone1 = '$variableone';
$groupone2 = '$variabletwo';
$groupone3 = '$variablethree';
$groupone4 = '$variablefour';
$groupone = array($groupone1, $groupone2, $groupone3, $groupone4, )
$grouptwo1 = '$variableone';
$grouptwo2 = '$variabletwo';
$grouptwo3 = '$variablethree';
$grouptwo4 = '$variablefour';
$grouptwo = array($grouptwo1, $grouptwo2, $grouptwo3, $grouptwo4, )
这是我真正想要的结果:
$groupone1 = '$variableone';
$groupone2 = '$variabletwo';
$groupone = array($groupone1, $groupone2)
$grouptwo1 = '$variablethree';
$grouptwo2 = '$variablefour';
$grouptwo = array($grouptwo1, $grouptwo2)
整个事情需要是动态的,因为我想添加任意数量的组和变量。
我几天来一直在寻找答案,并且已经问过两个不知道答案的人。也许你们可以提供帮助。谢谢!

只是澄清几点:
所以基本上我希望能够添加尽可能多的输入表单(我使用jQuery)来创建任意数量的组和变量,例如:
$ groupwuteva1 ='你好'; $ groupwuteva2 ='再见':
$ randomname1 ='green'; $ randomname2 ='blue'; $ randomname3 ='red';
$ blabla1 ='abc'; $ blabla2 ='xyz'; $ blabla3 ='123'; $ blabla4 ='bla';
我用作组名的任何内容都将在数组1中使用,例如我将一组称为“颜色”,我在该组中添加的变量是“蓝色”,“红色”和“绿色”。然后我会得到这段代码:
$ colors1 ='green'; $ colors2 ='blue'; $ colors3 ='red';
我希望这可以克服一些问题。到目前为止,感谢所有回复!

您可以将组名作为容器来存储其中的所有关联变量值。稍后,使用variable variables和implode()
函数处理您的html表单。

尝试以下形式:
//div[contains(span, 'TextA')]/following-sibling::div/span
和代码:
<form method="post" action="">
<?php foreach(array('groupone', 'grouptwo') as $num):?>
<div class="groupcontainer">
<br/><label>Groupe <?php echo $num;?>:</label><br/>
<input type="text" name="groupname[]" value="<?php echo $num;?>" /><br/>
<br/><label>Variable Group <?php echo $num;?>:</label><br/>
<input type="text" name="variable[<?php echo $num;?>][]" value="<?php echo uniqid();?>" />
<input type="text" name="variable[<?php echo $num;?>][]" value="<?php echo uniqid();?>" />
</div>
<br/>
<?php endforeach;?>
<input type="submit" name="submit" value="Submit" />
</form>
