Not passing variable

The below script for some reason isn't passing along the product_id variable.

$product_id=$_GET['product'];
session_start();
$error=$_SESSION['error'];
$content.='<div class="product_information_text review_form">
<div class="review_header">Write a Review for '.$product_name.'</div>
<form action="./review_process.php?product='.$product_id.'">
<p class="form_item"><label>Name:</label> <input type="text" name="review_name" size="30" /></p>';
if(isset($error[0])){$content.='<p class="red">This field is required.</p>';}
$content.='
<p class="form_item"><label>E-Mail:</label> <input type="text" name="review_email" size="30" /></p>
<p class="form_item"><label>Location:</label> <input type="text" name="review_location" size="30" /></p>
<p class="form_item"><label>Describe Yourself:</label> <input type="text" name="review_describe" size="30" /></p>
<p class="form_item"><label>Review Title:</label> <input type="text" name="review_title" size="30" /></p>
<p class="form_item"><label>Best Use of Product:</label> <input type="text" name="review_best_use" size="30" /></p>
<p class="form_item"><label>Product Pros:</label> <input type="text" name="review_pros" size="30" /></p>
<p class="form_item"><label>Product Cons:</label> <input type="text" name="review_cons" size="30" /></p>
<p class="form_item"><label>Product Rating:</label><br />
<div class="rating_radio"><input type="radio" name="review_product_rating" value="1" /> <br />1</div>
<div class="rating_radio"><input type="radio" name="review_product_rating" value="2" /> <br />2</div>
<div class="rating_radio"><input type="radio" name="review_product_rating" value="3" checked /> <br />3</div>
<div class="rating_radio"><input type="radio" name="review_product_rating" value="4" /> <br />4</div>
<div class="rating_radio"><input type="radio" name="review_product_rating" value="5" /> <br />5</div>
<div class="worst">(Worst)</div><div class="best">(Best)</div>
</p>
<p> </p>
<p class="form_item"><label>Comments on Product:</label><br />
<textarea name="review_text" rows="10" cols="60"></textarea>
</p>
<p><input type="submit" value="Submit" name="Submit" /></p>
</form>
</div>
';
session_unset();
session_destroy();

 

That code shows the proper product=$product_id value in the form action tag.

 

$product_id=$_GET['product_id'];

$review_name=$_POST['review_name'];
$review_name = stripslashes($review_name);
$review_name = mysql_real_escape_string($review_name);
if($review_name==""){
$error0=1;
}
else{
$error0=0;
}

$review_title=$_POST['review_title'];
$review_title = stripslashes($review_title);
$review_title = mysql_real_escape_string($review_title);
if($review_title==""){
$error1=1;
}
else{
$error1=0;
}

$review_email=$_POST['review_email'];
$review_email = stripslashes($review_email);
$review_email = mysql_real_escape_string($review_email);
if($review_email==""){
$error2=1;
}
else{
$error2=0;
}

$review_location=$_POST['review_location'];
$review_location = stripslashes($review_location);
$review_location = mysql_real_escape_string($review_location);
if($review_location==""){
$error3=1;
}
else{
$error3=0;
}

$review_describe=$_POST['review_describe'];
$review_describe = stripslashes($review_describe);
$review_describe = mysql_real_escape_string($review_describe);
if($review_describe==""){
$error4=1;
}
else{
$error4=0;
}

$review_best_use=$_POST['review_best_use'];
$review_best_use = stripslashes($review_best_use);
$review_best_use = mysql_real_escape_string($review_best_use);
if($review_best_use==""){
$error5=1;
}
else{
$error5=0;
}

$review_pros=$_POST['review_pros'];
$review_pros = stripslashes($review_pros);
$review_pros = mysql_real_escape_string($review_pros);
if($review_pros==""){
$error6=1;
}
else{
$error6=0;
}

$review_cons=$_POST['review_cons'];
$review_cons = stripslashes($review_cons);
$review_cons = mysql_real_escape_string($review_cons);
if($review_cons==""){
$error7=1;
}
else{
$error7=0;
}

$review_product_rating=$_POST['review_product_rating'];
$review_product_rating = stripslashes($review_product_rating);
$review_product_rating = mysql_real_escape_string($review_product_rating);

$review_text=$_POST['review_text'];
$review_text = stripslashes($review_text);
$review_text = mysql_real_escape_string($review_text);
if($review_text==""){
$error8=1;
}
else{
$error8=0;
}

$review_show="n";

date_default_timezone_set('US/Eastern');
$review_date = date("F j, Y, g:i a T");

$error="".$error0."".$error1."".$error2."".$error3."".$error4."".$error5."".$error6."".$error7."".$error8."";

if($error!=="000000000"){
session_start();
$_SESSION['error']=$error;
header("Location: ./store.php?product=".$product_id."#review");
}
else{
$sql="INSERT INTO $tbl_name3 (product_id, review_show, review_title, review_email, review_name, review_location, review_date, review_describe, review_best_use, review_pros, review_cons, review_product_rating, review_text) VALUES ('$product_id', '$review_show', '$review_title', '$review_email', '$review_name', '$review_location', '$review_date', '$review_describe', '$review_best_use', '$review_pros', '$review_cons', '$review_product_rating', '$review_text')";
mysql_query($sql);
echo "Thank You for submitting your review. It should appear on the site 
within 48 hours.";
}

 

The above redirects to store.php?product=#review with no product id. Ideas on why?

Your form doesn't have a method property on it. It my be passing the data as POST values (although I thought the default was GET). Anyway, try setting the method to method="get"

 

Wouldn't that put all the form's values in the URL? I don't want that. I just want the product_id carried in the URL. I did notice I forgot the method attribute and added it as POST. Still the same issue.

Yeah, my bad. I see you were appending it to the action value. Do a print_r($_GET) on the receiving page to validate if the value is there and there is a problem in the code.

I'm not sure which page is the sending page and which is the receiving page. BUt, I see you are not consistent in the naming ("product" vs. "product_id").

 

If the first script is posting to the second page, then your problem is that the form action is specified as follows:

<form action="./review_process.php?product='.$product_id.'">

 

And the second script is trying to reference the value using

$product_id=$_GET['product_id'];

If you use method='get' (or specify no method) in your <form> tag, you cannot put any get parameters on the end of the URL in the action="" attribute. Any get parameters on the end of the URL will be completely replaced by the form data.

 

You would need to use a hidden form field in this case.

wow.... I forgot that the $_GET[] is supposed to be the text before the equal sign.

 

I'll fixing that as soon as my host comes back up... it managed to crash as soon as I start trying to get this working.
