隱藏表單不會將變量傳遞給php

-4

即時通訊使用js將變量分配給隱藏表單的值。當我嘗試在PHP中訪問它時，沒有任何顯示。我知道JavaScript是正確的添加到窗體的值，但形成一些原因PHP只是不會得到它。繼承人的代碼：隱藏表單不會將變量傳遞給php

<html> 
<head> 

<script type="text/javascript" src="jquery.js"></script> 
<script type="text/javascript" src="textualizer.min.js"></script> 

</head> 

<style type="text/css"> 

#txtlzr{color:#585856; font-size:50px; width:1200px; height:100px; 
margin-left:10%; 
margin-top:80px; 
font-family:"futura"; 
position: fixed; 
} 
</style> 

<body> 


<div id="txtlzr"></div> 

<form name="kwoteForm" action="main.php" method="post"/> 
<input type="hidden" id="kwoteString" name="kwoteString" value="bob" /> 
<input class="kwote" type="text" maxlength="40" id="kwote"placeholder="Enter a something here."/> 
<input class="name" type="text" maxlength="17" id="name" placeholder="Enter your name."/> 
<input class="post" type="submit" value="Add comment" onclick="add_comment();" /> 
</form> 


<script language="javascript"> 



var COMMENTS_FOR_DISPLAY = new Array('OOOOOOO ITS WORKING : NICK'); 

// Adds a new comment, name pair to the Array feeding textualizer. 
function add_comment() { 
    // Retrieve values and add them to Array. 
    var new_comment = $('#kwote').val(); 
    var new_name = $('#name').val(); 

    COMMENTS_FOR_DISPLAY.push(new_comment + ': ' + new_name); 


    // Reset <input> fields. 
    $('#kwote').val(''); 
    $('#name').val(''); 

    //Take comment array and put it into a string. 
    var arrayAsString = JSON.stringify(COMMENTS_FOR_DISPLAY); 

    //Assign value of the string to a hidden form. 
    document.getElementById("kwoteString").value = arrayAsString; 

    //checks output. 
    alert(document.kwoteForm.kwoteString.value); 

    } 


$(document).ready(function() { 
    var txt = $('#txtlzr'); // The container in which to render the list 

    var options = { 
    duration: 5,   // Time (ms) each blurb will remain on screen 
    rearrangeDuration: 5, // Time a character takes to reach its position 
    effect: 'random',  // Animation effect the characters use to appear 
    centered: true  // Centers the text relative to its container 
    } 

    txt.textualizer(COMMENTS_FOR_DISPLAY); // textualize it! 
    txt.textualizer('start'); // start 
}); 



</script> 


</body> 
</html>

PHP：

<?php 
$saveKwote = $_POST["kwoteString"]; 
echo saveKwote; 
?>

由於某種原因，沒有什麼是迴盪！

我認爲這個錯字不在您的PHP代碼中？ 'echo saveKwote;'應該是'echo $ saveKwote'; – Gazillion 2012-04-17 19:02:16

'error_reporting（E_ALL）'是你的朋友!!!! – 2012-04-17 19:04:19

它是一個TYPO !!!，感謝GAZILION。這很令人尷尬。 – 2012-04-17 19:06:29

你需要改變：

echo saveKwote;

到

echo $saveKwote;

沒有美元符號（$），PHP試圖輸出它認爲是一個常數或不存在的功能，因此空輸出。

@Gazillion在第一條評論中已經指出 – Lion 2012-04-17 19:25:33

@Lion直到我發佈了答案後纔看到評論。 – 2012-04-17 19:26:32
