PHP电子商务页面循环未按预期列出项目

Question

I'm building a script which populates a page with products. Under each product is a "Buy" button. I looped through the products from the database, and the name and price and all other info turns up correctly. However, when I try to input that same info into the form with hidden fields I only get back the data from the first item from the list. Let me show you:

<div class="product-foo">
     //Shows up fine
     <p><?php echo product->name; ?></p> 
     <p><?php echo product->price; ?></p>
     <p><?php echo product->info; ?></p>

    //Only first iteration's info gets submitted, no matter which button I click
    <form method="post">
         <input type="hidden" name="product_name" value="<?php echo $product->name; ?>" > 
         <input type="hidden" name="product_price" value="<?php echo $product->price; ?>" >
         <input type="hidden" name="product_info" value="<?php echo $product->info; ?>" >
         <button type="submit" name="finalpost" class="btn btn-primary">Get Product</button>
    </form>
</div>

I thought that each form would be different, so when I clicked on a button on an item only the info for that item would go through, but it's always submitting the first item. I figure it may not work how I'm thinking it should work, but can anyone tell me why this is so and how I can easily resolve this?

Answer 1

Try to use this code for you button:

 <button type="submit" name="finalpost" class="btn btn-primary">Get Product</button>

It looks like you were missing the trailing > after your class definition. I suspect the 'view source' of the page would have showed all data, but since you broke the HTML it was being hidden from the browser view.

Another thing to consider - can you use:

  <input type='submit' value='Submit' /> 

instead of:

 <button> 

to further test? I suspect this will submit the right form data, but may not be acceptable if your button is calling JS and is doing more than submitting form data.
