ForEach Array Problem

[20pictures]

I am trying to rearrange an if...else statement to include an array. Originally, if the the statement were false (!) the else code would run.

Now I want the foreach statement to be true for an array code to run & if false the else code would run.

I am a bit confused by the (strtolower($build_list[$i]['cat_name']) element, which is probably why I have not had any success. I did try defining it as $value.

Original:

<?php
if(strtolower($build_list[$i]['cat_name'])!='test1'){
?>

<form>details not shown</form>

<?php 
 }else{
?>

<form>details not shown</form>

<?php 
 }
?>

My attempt:

<?php
$x=array("test1","test2");
if(strtolower($build_list[$i]['cat_name'])==$x)
foreach ($x as $value)
  {
?>

<form>details not shown</form>

<?php 
 }else{
?>

<form>details not shown</form>

<?php 
 }
?>

Any positive comment appreciated!

Have I explained this badly? There seem to be a lot of views but no offers of help.

i think you want in_array(), but im not really sure what you are trying to achieve.

Interesting. I just read up on in_array.

It seems that it will look for a variable in an array. I am trying to get all the variables in the array to run the code. I am coming unstuck as the original is an if...else statement & I seem to want foreach...else if there is such a thing?

I want to look at the variables, run the code if they are present, else run another code...

I have also notice extra php causing the original to increment

Thanks anyway!

Full Original Code:

<?php 
  for ($i=0;$i<sizeof($build_list);$i++){
?>

<?php
if(strtolower($build_list[$i]['cat_name'])!='test1'){
?>

<form>details not shown</form>

<?php }else{ ?>

<form>details not shown</form>

<?php } ?>

<?php } ?>

as i understand:

<?php

$x=array("test1","test2");

if(in_array(strtolower($build_list[$i]['cat_name']),$x)){

}else{ //not in array

}

?>

Thanks. That seemed to work fine.

When I try to take it one step further & include a second condition, it fails again:

<?php

$x=array("test1","test2");
if(in_array(strtolower($build_list[$i]['cat_name']),$x)){

}

$y=array("test3","test4");
elseif(in_array(strtolower($build_list[$i]['cat_name']),$y)){

}

else{ //not in array

}

?> 

Any comments?

[dagon]

<?php
$y = array("test3","test4");
$x = array("test1","test2");
if(in_array(strtolower($build_list[$i]['cat_name']),$x)){

}

elseif(in_array(strtolower($build_list[$i]['cat_name']),$y)){

}

else{ //not in array


}

?>

Thanks, that works too!

I had tried something similar but put the $y(array) after the $x(array)

It's not the order of assignment to $x and $y that matters. However, an elseif statement must ALWAYS follow an if or elseif statement, and the same goes for else.
Good

# assignments
$x = ...; $y=...;

if { }
elseif { }
else { }

Bad

if { }
# anything other than an elseif, such as...
$x = ...;
elseif { } # error - not precceded by if or elseif statement
$y = ...;
else { } # another error - else not preceeded by if or elseif statement.
