Add image for quantity available

[pette]

I want to add an image to show the quantity available of a product.

I want to calculate the rate of initial stock - the available quantity...

if the rate is > 70% I want to display an image if it is < 30 % I want to display an other image...

Is it possibile ?

thanks

You'll need another field to store the initial quantity, otherwise you simply can't take out the rate. You'll need a product override which grabs the field you need in the database. If you don't want to add those values manually, you'll also need to use some custom code/inputs from the back office (it's a bit too long to explain here, but I believe you can find info in the docs)

 

Finally, in product.tpl, locate the spot where the image must appear and use something like the following:

 

{math equation="a/b" a=$product->quantity b=$product->initial_quantity assign=quantity-rate}

{if $quantity_rate > 70}

<img src=".....image url">

{else if $quantity_rate > 30}

<img src="..another one">

{/if}

 

 

The trickierst part being, of course, the first one

Hi Nemo1,

i'm not able to add the initial values manually, so it's possible find the initial quantity?

thanks!

Hi,

but the variable {$product->initial_quantity} is it set?

it exists ?

thanks

 

 

And if the quantity is for every combination ?

thanks

No, it must be created as far as I know :/

 

You're right, the combinations thing introduces a new whole series of problems, since you'd need to add the intial quantity there too, and check it. No way to store in in the database with an out of the box prestashop i fear, you'll need some heavy core extensions

Thanks,

so it is not possible with the default variable.

the only possibility is to check with the available quantity with a javascript..

[NemoPS]

This would not give you the "initial" quantity either i fear

[pette]

No,

the only way is check if amount is > 3 or < 2 ....

yes, that's correct. You can setup a standard in your mind (like green image i you have > 40 or so). This wouldn't require modifications to the core
