All other configurations can be successful, but the first test program cannot be properly displayed & nbsp; index. php content: & nbsp; & lt ;? Php & nbsp; * load the configuration file * to ensure that the config file is correctly configured ..... Include. config. php; * sound Smarty template, tpl display problems
When I first started learning the Smarty template, all other configurations were successful, but the first test program could not be properly displayed.
Content in index. php ::
/* Load the configuration file */You can confirm that the configuration of the config file is correct .....
Include '../config. php ';
/* Declare an array */
$ Arr = array ('computerbook', 'name' => 'php advanced phase ', 'unit _ price' => array ('price' =>' $65.00 ', 'Unit '=> 'bene '));
/* Pass the title and array to the template */
$ Smarty-> assign ('title', 'Use Smarty to read the array ');
$ Smarty-> assign ('arr', $ arr );
/* Template page to be displayed */
$ Smarty-> display ('02/index. tpl ');
?>
Index in the tpl template file:


{% $ Title %}




Book purchase information:

{% * Obtain the first element value of the array using the index * %}
Book Category: {% $ arr [0] %}

{% * Use the key value to obtain the second array element value * %}
Book name: {%$ arr. name %}

{% * Use the key value to obtain the element value of the two-dimensional array * %}
Unit Price: {% $ arr. unit_price.price %}/{% $ arr. unit_price.unit %}



When accessed in a browser, the following output is displayed directly on the webpage:
Book purchase information:

{% * Obtain the first element value of the array using indexes * %} Book Category: {% $ arr [0] %}
{% * Use the key value to obtain the second array element value * %} book name: {% $ arr. name %}
{% * Use the key value to obtain the element value of the two-dimensional array * %} unit price: {% $ arr. unit_price.price %}/{% $ arr. unit_price.unit %}
