使用php for循环将表单值输出到xml

使用php for循环将表单值输出到xml,php,html,xml,Php,Html,Xml,因此,我在PHP中设置for循环以将HTML表单的内容输出到xml文件时遇到了问题。它可以在没有for循环的情况下工作,但不能使用。有什么想法吗?把我的头发扯下来 提前谢谢 //PHP Form <?php if (isset($_POST['lsr-submit'])) { } $str = '<?xml version="1.0" encoding="UTF-8"?><entrys></entrys>'; $xml = simplexml_load

//PHP Form

<?php
if (isset($_POST['lsr-submit']))
{
}
$str = '<?xml version="1.0" encoding="UTF-8"?><entrys></entrys>';
$xml = simplexml_load_string($str);
$i=1;
for ($i=1; $i <50; $i++) 
{ 
   $name = $_POST['Name_'.$i];
   $time = $_POST['Time_'.$i];
   $duration = $_POST['Duration_'.$i];
   $name = htmlentities($name, ENT_COMPAT, 'UTF-8', false);
   $time = htmlentities($time, ENT_COMPAT, 'UTF-8', false);
   $duration = htmlentities($duration, ENT_COMPAT, 'UTF-8', false);
   $xml->Slot = "";
   $xml->Slot->addChild('Name', $name);
   $xml->Slot->addChild('Time', $time);
   $xml->Slot->addChild('Duration', $duration);
}
$doc = new DOMDocument('1.0');
$doc->formatOutput = true;
$doc->preserveWhiteSpace = false;
$doc->loadXML($xml->asXML(), LIBXML_NOBLANKS);
$doc->save('../scSHARE/editor.xml');
print "<meta http-equiv=\"refresh\"     content=\"0;URL=return.php\">";
?>

//HTML Form

<?php
$xml=simplexml_load_file("../scSHARE/editor.xml");
$xml_array = (array) $xml;
$chunks=array_chunk($xml_array["Slot"], 7);
$i=1;
$l=1;
foreach($chunks as $bank) {
  ?> 
  <form name="form1" method="post" action="form.php">
     <div class="menu-toggle bank_<?php echo $i; ?>"  style="display:none;">
       <?php
       foreach($bank as $slot) { ?>
         <div class="row">
           <div class="small-12 column">
             <div class="small-6 column">
                Slot <?php echo $l?>
               <input type="text" name="Name_<?php echo $l;?>" value="<?php echo $slot->Name;?>">
             </div>
             <div class="small-6 column">
               <div class="row">

                 </div>
                 <div class="small-6 column">
                   Duration
                   <input type="text" name="Duration_<?php echo $l;?>" value="<?php echo $slot->Duration;?>">

<?php $i++;

//PHP表单
Slot->addChild('Name',$Name);
$xml->Slot->addChild('Time',$Time);
$xml->Slot->addChild('Duration',$Duration);
}
$doc=新DOMDocument('1.0');
$doc->formatOutput=true;
$doc->preserveWhiteSpace=false;
$doc->loadXML($xml->asXML(),LIBXML\u NOBLANKS);

打印“”;

//HTML表单
您可以使用以下语法:

for ($i=1; $i <50; $i++) 
{ 
    (...)
    $xml->Slot = "";
    $xml->Slot->addChild('Name', $name);
}

首先,你的
if(isset($\u POST['lsr-submit'])
没有效果。你需要把它应用到你所有的代码中,而不是什么都没有。啊,这是有道理的,它现在工作得很好。谢谢你的快速回复。非常感谢!
for ($i=1; $i <3; $i++) 
{ 
    (...)
    $slot = $xml->addChild( "Slot" );
    $slot->addChild( 'Name', $name );
    $slot->addChild( 'Time', $time );
    $slot->addChild( 'Duration', $duration );
}
if (isset($_POST['lsr-submit']))
{
    $str = '<?xml version="1.0" encoding="UTF-8"?><entrys></entrys>';
    (...)
    print "<meta http-equiv=\"refresh\"     content=\"0;URL=return.php\">";
}
