Adding Min Order QTY to tpl_pi_qty_input.php

[Portman]

Hi
I have added a minimum order qty field to my products database products_min_order_qty

I am trying to modify tpl_pi_qty_input.php to force the user to purchase no less than this number....

this is what I have done;

Code: Select all

<?php
		    $products_id = Text::input($_GET['pID'] ?? '');
			$grab_val = $GLOBALS['db']->query("SELECT products_min_order_qty FROM products WHERE products_id = " . (int)$products_id)->fetch_assoc();
			$product_min_order_qty = $grab_val['products_min_order_qty'];
			
			if ($product_min_order_qty == 0) {
				$min_qty = 1; 
			}	else {
				$min_qty = $product_min_order_qty;
			}
  ?>

<div class="col-sm-<?= $content_width; ?> text-right mt-2 pi-qty-input">

  <div class="input-group mb-2">
    <div class="input-group-prepend">
      <?php
      if (PI_QTY_INPUT_BUTTONS == 'True') {
        ?>
        <button class="btn btn-info spinner" type="button" data-spin="minus">
          <i class="fa fa-minus"></i>
        </button>
        <?php
      }
      else {
        ?>
          <div class="input-group-text"><?= PI_QTY_INPUT_BUTTON_TEXT; ?></div>
        <?php
      }
      ?>
    </div>
    <?php
    echo tep_draw_input_field('qty', $min_qty, 'min="1"', 'number', true, 'class="form-control form-control-lg" id="pi-qty-input"');
    
    if (PI_QTY_INPUT_BUTTONS == 'True') {
    ?>
    <div class="input-group-append">
      <button class="btn btn-info spinner" type="button" data-spin="plus">
        <i class="fa fa-plus"></i>
      </button>
    </div>
      <?php
    }
    ?>
  </div>

</div>

the bit that I added at the top does not read the value of products_min_order_qty... what have I done wrong here? do I have to define the variables in the main file rather than the tempalte file?(the if statement is a bit wierd I know but thats only because I set the default value to 0)

ALSO
in the input field, how do I change around the 'min="1"' bit so that it reflects $min_qty ? I've tried multiple things but cant get it to work

1. What is $_GET['pID'] when it doesn't work? Given the code that you have, this is the first question you should ask.
2. If you're using a modern version, you could just use the existing $GLOBALS['product']->get('min_order_qty') -- you don't have to load it separately.
3. This would run on the product_info.php page, where you have (int)$_GET['products_id'] not pID.
4. Modern version again:

Code: Select all

    $min_qty = $GLOBALS['product']->get('min_order_qty') ?? '1';
    echo (new Input('qty', ['min' => "$min_qty", 'class' => 'form-control form-control-lg', 'id' => 'pi-qty-input'], 'number'))->default_value("$min_qty");

Thank you so much for this ... I realised that although I had updated the pi modules I was using an outdated one in my override folder ... stupid mistake.

Can I ask for a bit of guidance on how to put something similar in the shopping cart? I assume I would be using a hook, but to be honest with you, no matter how hard I try I can't get my head around which hook I use where...

Obviously I want to stop the customer from reducing the qty of an item below the minimum quantity amount in the checkout product listing... with the same sort of warning that you get on pi_qty_input.php

Would I be using afterStart or startCheckout to controll this? or am I totally on the wrong track?

The quantity box is in the template.

The checkout hooks are on the pages checkout*.php

As above, override the tpl_ file.
Need to override /includes/modules/navbar/templates/tpl_nb_shopping_cart.php too.
We did this: app.php/addons/paid_addon/minimum_order ... r_product/

Thanks for your help... I have it working through modifying the template page and saving it in the override folder, but to be honest with you I really can't get my head around the hooks thing...

Can you give me any guidance on how to understand the hooks? as in is there documentation or a tutorial anywhere? I have looked at a youtube video by preston lord https://www.youtube.com/watch?v=bLd9m_uABYI&t=184s
which was great for sitewide things but if you are just controlling the nitty gritty of one line of text like this I get a bit lost

just controlling the nitty gritty of one line of text like this

Hooks aren't used for that, for tpl_ files use tpl_override.
