This time, i'll try to define the variable s on the template.

Due to the nature of smarty, it is originally recommended to do on the PHP side, but it is not said so in the field. In fact, variables are often created and addressed on the template side.

I think that there are various cases even if it is simply called a variable definition. Here are some examples of what we used in the field.

Defining variables in Smarty

If you simply want to create a variable called name, that's it.The second example is a short form. You can also use variables.It's okay if the variable is an array.

If it is a number, it is possible to calculate it.

Concatenate strings and variables, and combine variables

This is surprisingly convenient.You can create variables by attaching strings and variables. It is useful when you want to make more than one variable in a foreach statement.

Note the variable enclosure: the variable is enclosed in ` ;. It is not a single but a back quote. As you can imagine, the variables and variables are as follows.

It is a common count.

$count++ is not calculated. If you want to add in a foreach sentence, etc.

get value count in an array with smarty

I have an array called $mydata that looks like this:

I've assigned the array to smarty $smarty->assign("results", $mydata)

Now, in the template, I need to print how much of each "type" there is in the array. Can anyone help me do this?

• will there always be an index for type in each element in the array? and do you want to count all of them or just those with a value higher than zero? –  pythonian29033 Oct 18, 2012 at 17:50
• yes, there will. And the values are always higher than zero. –  Phil Oct 18, 2012 at 17:55

PHP 5.3, 5.4:

As of Smarty 3 you can do

You can also pipe it in Smarty 2 or 3:

To count up "type" values you'll have to walk through the array in either PHP or Smarty:

With PHP 5.5+ and Smarty 3 you can use the new array_column function:

• I do have Smarty 3, but how do I get the various numbers of "type" from {count($mydata)} ? –  Phil Oct 18, 2012 at 18:16

have you tried this?:

where count is passing the php function count()

• 1 It worked for me...but what is difference between |count and |@count –  Poonam Bhatt Jun 5, 2013 at 6:24
• @Poonam Bhatt, I actually don't know, when I answered this question I just did some research, coded a few lines and figured this, and that was quite a while ago –  pythonian29033 Jun 6, 2013 at 6:57
• 10 @PoonamBhatt quote: The "@" applies the modifier directly to the array instead of each individual element. see: Smarty FAQ –  juwens Sep 27, 2013 at 12:51
• So, to work as expected, should use @count to count an array… Thank you. –  Alex2php Jan 15, 2015 at 11:52
