[miyotz]

I have here my Javascript code that adds dynamic textbox (row) my problem is how can I save the values from the dynamic textbox to database using PHP script? Hope you can help me guys.. Thanks!

<script type="text/JavaScript"> 
  function addRow(r){ 
  var root = r.parentNode;//the root 
  var allRows = root.getElementsByTagName('tr');//the rows' collection 
  var cRow = allRows[0].cloneNode(true)//the clone of the 1st row 
  var cInp = cRow.getElementsByTagName('input');//the inputs' collection of the 1st row 
  for(var i=0;i<cInp.length;i++){//changes the inputs' names (indexes the names) 
  cInp[i].setAttribute('name',cInp[i].getAttribute('name')+'_'+(allRows.length+1)) 
  } 
  root.appendChild(cRow);
  } 
  function shownames(){ 
  var allInp=document.getElementsByTagName('input'); 
  for(var i=0;i<allInp.length;i++){ 
  alert(allInp[i].name) 
  } 
  } 
  </script> 

My HTML code:

  <form method="POST" action="#"> <table width="1024" border="0" cellspacing="6" cellpadding="0"> <tr>
      <td width="195"><div class="user"><input type="text" name="user_a" id="user"  tabindex="6"/></div></td> 
    <td width="410"><div class="reported"><input type="text" name="user_b" id="reported" tabindex="7"/></div></td> 
    <td width="399"><div class="reported"><input type="text" name="user_c" id="reported" tabindex="8"/></div></td> 
    <td width="10"><input name="button" type="button" value="+" onclick="addRow(this.parentNode.parentNode)"></td> </tr> </table> </form>

I don't see any PHP or MYSQL code in your script?

I hope you don't expect someone to write the PHP or MYSQL code for you?

I can tell you no one will write it!

If you don't understand PHP or MYSQL then you should learn it!

Hi

You can refer the below link for your reference

http://www.daniweb.com/web-development/php/threads/365673/how-to-add-dynamic-text-box-value-in-database

You're adding dynamic textboxes - so I suggest that you use array in name attribute, e.g.

<td width="195"><div class="user"><input type="text" name="user_a[]" id="user"  tabindex="6"/></div></td> 
    <td width="410"><div class="reported"><input type="text" name="user_b[]" id="reported" tabindex="7"/></div></td> 
    <td width="399"><div class="reported"><input type="text" name="user_c[]" id="reported" tabindex="8"/></div></td>

Your ids are wrong and if you need to use them, they will have to be made unique. You can't have identical ids in a page. Also, I wonder about the tabindexes. These will also be duplicated? If so, could be a prob - you tab from user_a to user_a - not user_a to user_b

you should probalbly not be cloning the row though you should build a clean row and append it
document.createNewElement("tr")...

using allRows length input.tabIndex=allRows.length

I'd wrap the add row into a function:

var rowno = 1; var tabindex = 8;
function addRow(){
    //increment rowno every time this runs - so you can make unique ids if req'd
    //concatenate the tablerow cells while -
    //increment tabindex for each textbox added
    //return the tablerow
}

Why not use a library like jquery or prototype.. You could accomplish the samething with few and robust inline code.

Show your code first.
