 <form name="search" method="post" action="<?php $_server['php_self'];?>">  seach for: <input type="text" name="find" /> in   <select name="field">  <option value="english">english</option>  <option value="spanish">spanish</option>  </select>  <input type="hidden" name="searching" value="yes" />  <input type="submit" name="search" value="search" />  </form>    <?php $options = array('english'=> array('1' => 'one', '2' => 'two'), 'spanish' =>array('1'=>'uno', '2'=>'dos'));  if (($_post['find'] == '1')&& ($_post['field'] == 'english')){     echo $options['english']['1']; } ?> 

i want have function, when user input '1' , seclet 'english', show one, when user input '1' sellect 'spanish', show uno, , on.

questions:

1. is there way replace line?

 if (($_post['find'] == '1')&& ($_post['field'] == 'english')){       echo $options['english']['1'];     } 

imagine if have number 1 100, impossible me repete these codes(==1 && ==english, ==2 && == english...).

2 if u run script, shows

notice: undefined index: find ...

what probem , how fix it?

first point :

<form name="search" method="post" action="<?php $_server['php_self'];?>"> 

the <?php $_server['php_self'];?> nothing. shall have use echo here. nevertheless, bug not show because it's default behaviour form call script @ $_server['php_self'] when action attribute not set.

also :

<input type="hidden" name="searching" value="yes" /> 

seems useless.

second point :

of course don't want parse each possible choice in static fashion. you'll use abstraction , dynamic behavior.

you have 1 array index language , each sub array gives word used each number. hence, have rule , computations :

<?php $input = trim($_post['find']); $language = $_post['field']; $output = $options[$language][$input]; echo $output; ?> 

that's minimal code. please don't use 'as is'. you'll have @ least check if keys exist , provide adequate error messages.
