Attributes

$content

This attribute sets the text as it will appear in the Index entry. Text should be UTF-8 encoded.

$content cannot contain any of the characters: <, >, &, ' or " and must use the appropriate HTML entities e.g. <indexentry content="&lt; 40" />

It is recommended that you use htmlspecialchars('Content', ENT_QUOTES) for this.

This attribute sets the text used as a cross-reference. Text should be UTF-8 encoded.

$xref cannot contain any of the characters: <, >, &, ' or " and must use the appropriate HTML entities e.g. <indexentry xref="&lt; 40" />

It is recommended that you use e.g. htmlspecialchars($xref, ENT_QUOTES) for this.

Text entries passed in the form xref="Subject:Subcategory" will appear in the Index as “Subject, Subcategory”

<?php
$mpdf = new \Mpdf\Mpdf();

$mpdf->WriteHTML('Beginning bit of document...');
$mpdf->WriteHTML('Your text which refers 
to a buffalo,<indexentry content="Buffalo" /> which you would like to see in the Index');

$mpdf->AddPage();
$mpdf->WriteHTML('<h2>Index</h2>',2);
$mpdf->CreateIndex(2, '', '', 3, 1, '', 5, 'serif','sans-serif');
$mpdf->Output();

Example #2

<?php

$mpdf->WriteHTML('<indexentry content="Dromedary" xref="Camel:types" />The dromedary 
is a type of camel');

// Dromedary - see Camel, types

Notes

Recommended placement of Index Entries is just after the first word following the opening tag of the block element:


<h2>First<indexentry... /> word of a heading or block</h2>

or alternatively just after the opening tag of the block element:


<h2><indexentry... />Heading or block</h2>

or just after a word to be marked:


    ... this is a word<indexentry... /> in the middle of text to be marked ...
