Hi,

I have been trying unsuccessfully to get the output from the code below into a single variable. I need to be able to pass the output from the  info shown here in an email receipt. I have been trying to get the output into a hidden form field which I could then pass along. Would this be a good way to do it? If so how?
<?php
  for($i=0; $i<=4; $i++)
    if($_REQUEST['L_QTY'.$i]>=1)
    {
      ?>
      <tr>
        <td align="left" valign="top"><?=$_REQUEST['L_QTY'.$i]?></td>
        <td align="left" valign="top"> </td>
        <td align="left" valign="top"><?=$_REQUEST['L_NAME'.$i]?></td>
        <td align="left" valign="top"> </td>
        <td align="left" valign="top"><?=$_REQUEST['L_DESC'.$i]?></td>
      </tr>
      <?php
    }
  ?>

You mean

<?php
  $htmlString = "<table>";
  for($i=0; $i<=4; $i++) {
    if($_REQUEST['L_QTY'.$i]>=1)
    {
      $htmlString .= '<tr>';
      $htmlString .= '<td align="left" valign="top">'.$_REQUEST['L_QTY'.$i].'</td>';
      $htmlString .= '<td align="left" valign="top"> </td>';
      $htmlString .= '<td align="left" valign="top">'.$_REQUEST['L_NAME'.$i].'</td>';
      $htmlString .= '<td align="left" valign="top"> </td>';
      $htmlString .= '<td align="left" valign="top">'.$_REQUEST['L_DESC'.$i].'</td>';
      $htmlString .= '</tr>';
    }
  }
  $htmlString.='</table>';
  echo $htmlString;
?>

or even

<?php
  $htmlString = "<table>";
  for($i=0; $i<=4; $i++) {
    if($_REQUEST['L_QTY'.$i]>=1)
    {
      $htmlString .= '<tr valign="top">';
      $htmlString .= '<td>'.$_REQUEST['L_QTY'.$i].'</td>';
      $htmlString .= '<td>&nbsp;</td>';
      $htmlString .= '<td>'.$_REQUEST['L_NAME'.$i].'</td>';
      $htmlString .= '<td>&nbsp;</td>';
      $htmlString .= '<td>'.$_REQUEST['L_DESC'.$i].'</td>';
      $htmlString .= '</tr>';
    }
  }
  $htmlString.='</table>';
  echo $htmlString;
?>

Thanks mplungjan

I think that might be the right idea, but I still cannot seem to get the value for $htmlString to pass to the next page. Here is how I formatted my hidden input.




<input type="hidden" name="products" value="<? $htmlString ?>" />

I don't need to pass along the entire <table>, only the values of ['L_QTY'.$i] ['L_NAME'.$i] ['L_DESC'.$i]

No, that didn't work either, I did manage to figure out how to pass along all the variables, however I am now having trouble writing an if statement to only pass along the variables that have a L_QTY value that is greater than 0
<input type="hidden" name="L_QTY0" value="<? echo $_REQUEST['L_QTY0']; ?>" />
<input type="hidden" name="L_NAME0" value="<? echo $_REQUEST['L_NAME0']; ?>" />
<input type="hidden" name="L_DESC0" value="<? echo $_REQUEST['L_DESC0']; ?>" />
<input type="hidden" name="L_QTY1" value="<? echo $_REQUEST['L_QTY1']; ?>" />
<input type="hidden" name="L_NAME1" value="<? echo $_REQUEST['L_NAME1']; ?>" />
<input type="hidden" name="L_DESC1" value="<? echo $_REQUEST['L_DESC1']; ?>" />
<input type="hidden" name="L_QTY2" value="<? echo $_REQUEST['L_QTY2']; ?>" />
<input type="hidden" name="L_NAME2" value="<? echo $_REQUEST['L_NAME2']; ?>" />
<input type="hidden" name="L_DESC2" value="<? echo $_REQUEST['L_DESC2']; ?>" />
<input type="hidden" name="L_QTY3" value="<? echo $_REQUEST['L_QTY3']; ?>" />
<input type="hidden" name="L_NAME3" value="<? echo $_REQUEST['L_NAME3']; ?>" />
<input type="hidden" name="L_DESC3" value="<? echo $_REQUEST['L_DESC3']; ?>" />
<input type="hidden" name="L_QTY4" value="<? echo $_REQUEST['L_QTY4']; ?>" />
<input type="hidden" name="L_NAME4" value="<? echo $_REQUEST['L_NAME4']; ?>" />
<input type="hidden" name="L_DESC4" value="<? echo $_REQUEST['L_DESC4']; ?>" />

If you add the [], php makes it into an array for you

If you need to check a string you might want to make it a number first - I do not have the php syntax to do that

I don't know exaktly where the problem is. You have to make a hidden input field for every variable and not for the hole html code.

If you need this html code more than once, you can make a function.

But if it is only a display site, you can send your mail direktly or not?

Try this:
<?php
  for($i=0; $i<=4; $i++)
    if($_REQUEST['L_QTY'.$i]>=1)
    {
      ?>
      <input type="hidden" name="<?=$_REQUEST['L_QTY'.$i]?>" value="<?=$_REQUEST['L_QTY'.$i]?>" />
      <input type="hidden" name="<?=$_REQUEST['L_NAME'.$i]?>" value="<?=$_REQUEST['L_NAME'.$i]?>" />
      <input type="hidden" name="<?=$_REQUEST['L_DESC'.$i]?>" value="<?=$_REQUEST['L_DESC'.$i]?>" />
      <?php
    }
  ?>

That does not make sense. To pass the value as name.

But that is what I did, I just used the smarter [] notation which creates PHP arrays

Try this - convert the quantity to an integer using intval:



<?php
  for($i=0; $i<=4; $i++) {
    if(intval($_REQUEST['L_QTY'.$i])>=1)
    { ?>
      <input type="hidden" name="L_QTY[]" value="<? echo $_REQUEST['L_QTY'.$i]; ?>">
      <input type="hidden" name="L_NAME[]" value="<? echo $_REQUEST['L_NAME'.$i]; ?>">
      <input type="hidden" name="L_DESC[]" value="<? echo $_REQUEST['L_DESC'.$i]; ?>">
    <? } 
  }?>
 
e.g.
 
<input type="hidden" name="L_QTY[]" value="First filled quantity">
<input type="hidden" name="L_NAME[]" value="First filled name">
<input type="hidden" name="L_DESC[]" value="First filled description">
<input type="hidden" name="L_QTY[]" value="Second filled quantity">
<input type="hidden" name="L_NAME[]" value="Second filled name">
<input type="hidden" name="L_DESC[]" value="Second filled description">

My english is not very good.

I like the [] notation too. But maybe he need the combination of the name (1,2,3,4) and the value.

<?php
  for($i=0; $i<=4; $i++) {
    if(intval($_REQUEST['L_QTY'.$i])>=1)
    { ?>
      <input type="hidden" name="L_QTY[<?=$i?>]" value="<? echo $_REQUEST['L_QTY'.$i]; ?>">
      <input type="hidden" name="L_NAME[<?=$i?>]" value="<? echo $_REQUEST['L_NAME'.$i]; ?>">
      <input type="hidden" name="L_DESC[<?=$i?>]" value="<? echo $_REQUEST['L_DESC'.$i]; ?>">
    <? } 
  }?>
