動態行插入表中通過php

Question

我有3行。哪些是動態創建的。如果我們點擊添加更多那麼所有三個字段都是動態創建的。它正常工作。

但我想通過mysql查詢動態地將這些字段插入到表中。我嘗試過，但它不起作用。請幫助任何人解決它。謝謝。

    <script type="text/javascript"> 
    var rowCount = 1; 

    window.addMoreRows = function(frm) { 
    rowCount++; 
     var recRow = '<div id="rowCount' + rowCount + '"><div class="col-sm-3 text-left">College Name:</div><div class = "col-sm-9"><input type="text" name = "collegename[]" placeholder = "College Name" class = "form-control"/></div><div class = "col-sm-3 text-left" > Affiliated University: </div><div class = "col-sm-9" ><input type = "text" name = "univ[]" placeholder = "Affiliated University" class = "form-control"/> </div><div class = "col-sm-3 text-left" > Course Name: </div> <div class = "col-sm-9" ><input type = "text" name = "cname[]" placeholder = "Course Name" class = "form-control"/></div><div class = "col-sm-3 text-left" > Major & Subject: </div><div class = "col-sm-9"><input type = "text" name = "msub[]" placeholder = "Major Subject" class = "form-control"/></div><div class = "col-sm-3 text-left"> Final & Percentage: </div><div class = "col-sm-9"><input type = "text" name = "fper[]" placeholder = "Final Percentage" class = "form-control"/></div><a href = "javascript:void(0);" onclick = "removeRow (' + rowCount + ');" >Delete</a></div> ';

我找不到，你叫你的輸入字段。

根據要從$ _POST參數中檢索的數組命名您提交的輸入字段。

<input name="dynfields[]"/> 

括號告訴PHP，提交的值是數組的一部分。 在你編輯的問題中，HTML會是這樣的。

<tr> 
    <td><input name="dynfields[]" type="text" value="" size="17%"/></td> 
    <td><input name="dynfields1[]" type="text" value="" /></td> 
    <td><input name="dynfields2[]" type="text" value="" /></td> 
</tr> 
<tr> 
    <td><input name="dynfields[]" type="text" value="" size="17%"/></td> 
    <td><input name="dynfields1[]" type="text" value="" /></td> 
    <td><input name="dynfields2[]" type="text" value="" /></td> 
</tr> 
(...) 

提交，你應該能夠訪問3個單獨的陣列形式後：

$_POST['dynfields']; 
$_POST['dynfields1']; 
$_POST['dynfields2'];
