Sessions Help

[Lukey]

I have created a database with a table called houses with various house information as fields.

My search page is working fine and loads up each result in a separate table using a loop:

 

while($newarray = mysqli_fetch_array($result, MYSQLI_ASSOC))
	{
	$rname = $newarray["hname"];
	$rcountry = $newarray["hcountry"];
	$rbeds = $newarray["beds"];
	$rprice = $newarray["hprice"];


	?>
	<table cellspacing="0" cellpadding="4" border="1" width="80%" bgColor="#ccff99" borderColor="#ffcccc">
  <tr><form action="http://localhost/housedetail.php" method="post">




    <!-- Row 1 Column 1 -->
    <td>
    <img src="C:\Documents and Settings\Lukey\Desktop\MAIN PROJECT\<?php echo($rname);?>.jpg">
     
      
      
    </td>
    <!-- Row 1 Column 2 -->
    <td><div align="left">
      <?php 
      echo"<li>$rname</li><br/>";
      echo"<li>$rcountry</li><br/>";
      echo"<li>$rbeds Bedrooms</li><br/>";
      echo"<li><i>£ $rprice</i></li><br/>";
   session_start();
      $_SESSION['housename'] = $rname;
      
      
      
      ?></div>
    </td>
    <!-- Row 1 Column 3 -->
    <td>
    <center><h5>Please Click the Button for futher details</h5><br/>
      <input type="submit" value=" House Details "/></center>
    </td>
  </tr>
  </form>
</table>



	<?php
	echo"<br/>";

	}

 

However i have a button in each result table which links to a php script that loads up a page with further details of the house.

I decided to use SESSIONS to pass the housename to the next script so i can retrive the data and display it BUT i can only start one session at a time and because it loops i get errors on my page:

 

Notice: A session had already been started - ignoring session_start() in C:\Program Files\Apache Group\Apache2\htdocs\housesearch.php on line 210

 

 

Any help would be most appreciated!

Ummm yeah why would you need more than one session going at a time?

 

Since it's an array you can just use $_SESSION['somevar'] = "something"; $_SESSION['someothervar'] = "Somethineelse"; etcetera.

 

You should be able to safely delete the session_start on line 210 of housesearch.php, but I didn't read your code... so.... lol

And try to put ur session at very top of the page.

And use one session at a time in one page, mean script.

 

<?php
session_start();
Rest of ur code.
?>

Aha thanks that was a stupid thing to miss however it has given me a different problem in that the only variable it is passing to the next script is the last record of the results and not the correct one clicked

 

As you can see in the attached screenshot i am aiming to get the button to pass the correct housename across.

BUMP

 

Anyone have an idea how i can split the array up into so that i can pass the correct housename variable to the next script?

This should work...

 

print $array[0];

 

Depending on how many array's you have, the variable is either 0 - ** where star is being the last one.

 

if you want to use only 0, 3 and 7, then it would be

 

echo $array[0] $array[3] $array[7];

Its ok mate i bodged my way around it by adding a html hidden type input and putting each housename into that as it goes through the loop.  Each hidden box with the variable value has a corresponding button and it works!
