Well, I am about to finish online booking processing.

I am stack with the following problem.

I have adult_fname as an array.I want to validate it. I want to display the submit value if the any of the field is empty. It just display as an array() .


Let say there are 3 input boxes with name adult_fname[], if u fill in only 2 and left one, it should display error and shows what u typed for other two fileds.

Its the same concept as single variable. let say u have phone and name input box. And they are compulsory. If u just fill in name, it shows error and redisplay what u typed for name field . But what u do when u have array , how do u redisplay it..




Code:

   {if $adult <>"0"}
{validate field="adult_fname" criteria="notEmpty"  transform="trim" message=" * Please enter adult's name."}

   <fieldset><legend>Adult(s) name</legend>
   <table width=100%>
   {section name="myLoop" start=0 loop=$adult}
   <tr><td> First Name : <input type="text" name="adult_fname[]" size="20"  [color=red]value="{$adult_fname|escape}"[/color]></td><td>Last Name : <input type="text" name="adult_lname[]" size="20"></td></tr>
   {/section}
   </table>
   </fieldset>
   {/if}

You should be able to validate an array of data and it will fail if one is empty, however you will have only one error message. A custom validator could be written to distinguish separate error messages. As for redrawing the form, that is a matter of looping over the array and displaying them, or just doing it statically:

<input type=text name=foobar[] value="{$foobar[0]|escape}">
<input type=text name=foobar[] value="{$foobar[1]|escape}">
<input type=text name=foobar[] value="{$foobar[2]|escape}">

Thank you. I want to display dynamically,

Code:

{if $adult <>"0"
{section name="myLoop" start=0 loop=$adult}
First Name : <input type="text" name="adult_fname[]" size="20"  value="{$adult_fname[{$start}]|escape}">
   {/section}
{/if}


instead of
Code:

{if $adult <>"0"
First Name : <input type="text" name="adult_fname[]" size="20"  value="{$adult_fname[0]|escape}">
First Name : <input type="text" name="adult_fname[]" size="20"  value="{$adult_fname[1]|escape}">
First Name : <input type="text" name="adult_fname[]" size="20"  value="{$adult_fname[2]|escape}">

{/if}



Because number of $adult is some time 1, some time 5 .. it can be anything..

You want something like this:

Code:
{section name="myLoop" loop=$adult_fname}
First Name : <input type="text" name="adult_fname[]" size="20"  value="{$adult_fname[myLoop]|escape}">
{/section}
