[SOLVED] DropDown Select

[Minase]

hy there i do have a dropdown

<select name="test" size=1>
<option value="2">123</option>
<option value="3">test</option>
<option value="4">something</option>

 

and a variable $a.

i want if variable $a == 4 then the dropdown box to have the selected input 4.

 

and another problem

if $b = "abcd";

i want to search in this variable for values like

if $b has "a" than $a1 = 1;

 

hope you understand

thanks

<option selected="selected" value="<?php echo $a; ?>"><?php echo $a; ?></option>

[Minase]

you did not understand me

if $a == 4 then the option number 4 to be selected.

[DeanWhitehouse]

Yes i did understand you, i have shown you how to make something selected, i am not writing it all for you. Please try your self.

 

All you need to do is add an if statment.

 

There are two ways ,

first:

<option selected="selected" value="<?php if($a == 4) echo 4; ?>"><?php if($a == 4) echo 4; ?></option>

second:

<option value="2" <?php if($a == 2) echo "selected='selected'";?>>123</option>

<option value="3" <?php if($a == 3) echo "selected='selected'";?>>test</option>

<option value="4" <?php if($a == 4) echo "selected='selected'";?>>something</option>

thank you very much but how can i check if a variable contain some values?

like in my first post?thanks

[DeanWhitehouse]

this may do it

http://uk3.php.net/manual/en/function.stristr.php

[Minase]

that doesnt help very much

i will explain what i must do.

i must put every character of the string into variables.

every character into its own variable.

thanks

*bump*

[peuge]

To check if a variable contains some values try using http://www.php.net/preg_match

[Minase]

maybe someone have a better ideea how to do this .let me explain:

 

i do have a variable $access

$access = "1234567";

and 7 checkboxes with name from 1-7 i want if the variable contain 134 the checkboxes with name 1,3,4 to be checked.

but i cant figure out what is the best method

i was thinking to split those numbers and use an if statement,but i cant make it to split so anyone has ideeas?

thanks

<?php
if ($a  == (4)){
$a = "selected";
}else{
$a = "";
}
?>

<select name="test" size=1>
<option  value="2">123</option>
<option value="3">test</option>
<option <?php echo $a; ?> value="4">something</option>
</select>

 

 

[Minase]

your code is easy if it was just 1 checkbox no problem but they are seven and it can be combinated....

[DeanWhitehouse]

you have to try and do it on your own, not expect us to write it all for you. Go on what we have given you , and try to figure it out.

[Minase]

the ideea how to do it code is easy to write,but i dont have the ideea....
