Error comparing IF statements

[uchejava]

I am trying to compare IF statements.

if ($_POST['price'] =="see all"){
//show okolo 
} 
else if ($_POST["accommodation"] =="see all"){
//show chibuzo 
} 

This works but as soon as I add:

else if ($_POST['price'] =="see all" AND $_POST['accommodation"]=="see all"){ 
//show henry 
} 

This stuff does not work, it now shows "okolo" instead of "henry

That's right as the first if condition is satisfield.

Try putting the last one at the start instead.

if ($_POST['price'] =="see all" AND $_POST['accommodation"]=="see all")
{ 
    //show henry    
}
else if ($_POST['price'] =="see all")
{
    //show okolo 
} 
else if ($_POST["accommodation"] =="see all")
{
    //show chibuzo 
}

In addition, there is a small typo with quotes:

$_POST['accommodation"]

Use single quotes or double quotes, not both together:

$_POST['accommodation'] # or
$_POST["accommodation"]

Bye!

I am still having the same error

if ($_POST['accommodation'] == "see all" AND $_POST['price']=="see all"){

}        

else if ($_POST['accommodation']=="see all"){

}

else if ($_POST['price']=="see all"){

}

Works fine for me, try to trim the input, if you get a space at the beginning or at the end of the string then the comparison will fail, so before the statements do:

$_POST = array_map('trim', $_POST);

if ($_POST['accommodation'] == "see all" && $_POST['price']=="see all"){

}

Use && instead of and because it is php.

Just a tip. If you are collecting this data from select dropdowns, then it's usually easier to set the 'see all' value to '', that way you can do something like:

if(!$_POST['accommodation'] && !$_POST['price'])

From the select:

<select name="accommodation">
    <option value="">All<option>
    ...other options prob from DB...
</select>

Also @Nilesh_4

Hi! In PHP you can use both. But there's to say that && has an higher precedence than AND, which defines how the conditions are grouped. So for example:

<?php

    $a = true;
    $b = true;
    $c = false;

    $d = $a === true && $b === true AND $c === true;
    echo var_dump($d);

    $d = $a === true && $b === true && $c === true; 
    echo var_dump($d);

Outputs:

test #1
bool(true)

test #2
bool(false)

If the conditions are set into an IF statement, instead of being assigned to a variable, the expression returns false in both cases.
