Im after a little bit of help with two things in my code.

 

www.1pw.co.uk/demo2.php

 

1) getting an image to appear opposed to just the filename.

 

where and how in my code should i put <img src="filename" />

in the img column of mysql  database i am just listing filenames.  should i wrap these in the html above instead?

 

2) how can i get my calculator to behave?

 

i get the correct tally when checking out (using order.php), but as you will see from the link provided the calculator does not work properly, in demo2.php

 

-- addtocart2.php --

 

<?php

define('INCLUDE_CHECK',1);
require "../connect2.php";

if(!$_POST['img']) die("There is no such product!");

$img=mysql_real_escape_string(end(explode('/',$_POST['img'])));
$row=mysql_fetch_assoc(mysql_query("SELECT * FROM internet_shop WHERE img='".$img."'"));

$jsonArr = array('img' => $row['img'], 'status' => 1, 'id' => $row['id'], 'price' => $row['price'], 'txt' => ' 

<table width="100%" id="table_'.$row['id'].'">  
<tr>   
<td width="40%">'.$row['img'].'</td>   
<td width="20%">'.$row['name'].'</td>    
<td width="10%">$'.$row['price'].'</td>    
<td width="15%">
<select name="'.$row['id'].'_cnt" id="'.$row['id'].'_cnt" onchange="change('.$row['id'].');">	
<option value="1">1</option>	
<option value="2">2</option>	
<option value="3">3</option></slect>		
</td>	
<td width="15%"><a href="#" onclick="remove('.$row['id'].');return false;" class="remove">remove</a></td>  
</tr>
</table>');

echo json_encode($jsonArr);

?>

As to the first question about getting an image to appear in my table.

ive added 'thumb' => $row['thumb']  to my json array, aswell as a thumb column in my mysql database.

in the row containing my dafodil image ive added - <img src="http://www.1pw.co.uk/img/products/yellowdaf.jpg" height="20px" width="20px />

ok, my images appear fine.

 

Im still confused however why my calculator has stopped working properly since creating the json array.

 

This is my code before I created the json array. (Calulator worked fine).  Im really confused!?!?!?!

 

echo '{status:1,id:'.$row['id'].',price:'.$row['price'].',txt:\'\
\
<table width="100%" id="table_'.$row['id'].'">\
  <tr>\
    <td width="60%">'.$row['name'].'</td>\
    <td width="10%">$'.$row['price'].'</td>\
    <td width="15%"><select name="'.$row['id'].'_cnt" id="'.$row['id'].'_cnt" onchange="change('.$row['id'].');">\
<option value="1">1</option>\
<option value="2">2</option>\
<option value="3">3</option></slect>\
\
</td>\
<td width="15%"><a href="#" onclick="remove('.$row['id'].');return false;" class="remove">remove</a></td>\
  </tr>\
</table>\'}';
