How to know which hook display pdf is being displayed in tpl files

[ptityop]

Hello,

I am trying to work out how to know which hooks are being displayed in the invoice or other tpl files as shown in the code below ... the only info is Hook_display_pdf but how do we know which pdf is being displayed , how the order is determined .... other than obviously printing the invoice ... what is the logic behind this ? Thanks in advance ...

 

<!-- Hook -->
	{if isset($HOOK_DISPLAY_PDF)}
	<tr>
		<td colspan="12" height="30">&nbsp;</td>
	</tr>

	<tr>
		<td colspan="2">&nbsp;</td>
		<td colspan="10">
			{$HOOK_DISPLAY_PDF}
		</td>
	</tr>
	{/if}

Hi, i don't understand well.

Do you want to know how the invoice is created? 

And which hook are used to do create it?

I don't  understand what the command {$HOOK_DISPLAY_PDF} does either me.

I can tell you that when the invoice pdf is created this is using some tpl together.

You can found them in directory -> /pdf

 

In the file public_html/classes/pdf/HTMLTemplateInvoice.php i saw this instructions:

$tpls = [
            'style_tab' => $this->smarty->fetch($this->getTemplate('invoice.style-tab')),
            'addresses_tab' => $this->smarty->fetch($this->getTemplate('invoice.addresses-tab')),
            'summary_tab' => $this->smarty->fetch($this->getTemplate('invoice.summary-tab')),
            'product_tab' => $this->smarty->fetch($this->getTemplate('invoice.product-tab')),
            'tax_tab' => $this->getTaxTabContent(),
            'payment_tab' => $this->smarty->fetch($this->getTemplate('invoice.payment-tab')),
            'note_tab' => $this->smarty->fetch($this->getTemplate('invoice.note-tab')),
            'total_tab' => $this->smarty->fetch($this->getTemplate('invoice.total-tab')),
            'shipping_tab' => $this->smarty->fetch($this->getTemplate('invoice.shipping-tab')),
        ];
 

I tried to copy these tpl and header.tpl + footer.tpl in a new directory -> themes/name-of-theme-child/pdf 

After i modified these files i saw that my changes were successfully done in the invoice pdf.

That was really helpul !! thanks ... Although I still do not get what the {$HOOK_DISPLAY_PDF}
 refers to, i learned somehitng else along the way :-)

$HOOK_DISPLAY_PDF is not hook !!

It's a smarty variable.
You can find it in ./classes/pdf/HTMLTemplate.php

 

Find it:

/classes/pdf/HTMLTemplate.php

/pdf/delivery-slip.tpl

/pdf/invoice-b2b.tpl

/pdf/invoice.tpl

/pdf/order-return.tpl

/pdf/order-slip.tpl
