[RESOLVED] Quick PHP help please :D?

**kobbles11** · 01-29-2013 06:25 PM

Hi, just trying something out (im new to PHP) so far ill show you the relevant bits. Im good with html and css so nothing wrong there

ok so:

// top of pahe within php tags

$region = Array ('EU', 'NON EU');



<form action="" method="POST" name="region">
<select name="region" id="select_type" onchange="document.region.submit()">
<option> ---Please Select--- </option>
<?php

foreach($region as $key => $value) {

echo '<option value="'.$key.'" .$_POST['region'] == '$key' ? 'selected' : '>'.$value.'</option>';

}

?>

</select>
</form>

i get this error on the page

:

Parse error: syntax error, unexpected 'region' (T_STRING), expecting ',' or ';' in C:\xampp\htdocs\xampp\Start\trial\index.… on line 86

Not sure what to do now any help would be appreciated

Thanks

When posting code, please use the appropriate formatting codes described in the FAQs. As it happens, in this case doing so would have provided a clue as to your problem:

PHP Code:


 echo '<option value="'.$key.'" .$_POST['region'] == '$key' ? 'selected' : '>'.$value.'</option>';

You're missing a ' after the second " (since you haven't written any abbreviations with apostrophes, you'd expect to count an even number of them in the line - half of them opening quotes, half of them closing).

I knew i shouldve done that, with my haste didnt see the option...

OK, ive changed it, i get no error now but my result (creating <option> tags from my array) isnt showing up...

if anyone thinks its better i past my whole page let me know and ill do it.

Thanks

Can you show us a fixed copy of the PHP code snippet above? Also, can you show us the resulting output it generates?

**kobbles11** · 01-30-2013 03:17 AM

its actually a short page ill just put it all here:

i dont know if i wrapped the code right as its my first time so if its wrong...

All i got on the page is 2 dropdowns the first one getting for a certain array and the second one is meant to choose an erray depending on the first one...

PHP Code:


<?php





$region =             Array ('EU', 'NON EU');

$EUcountries =         Array( 'UK', 'Spain');

$NONEUcountries =     Array( 'Austria', 'Australia');



?>

        <style>

        

        #container {

        border: 1px solid grey;

        width: 900px;

        margin: 0 auto;

        min-height: 200px;

        }

        

        .header {

        text-align: center;

        text-transform:uppercase;

        font-size: 35px;

        float: left;

        top: 30px;

        left: 30px;

        width: 200px;

        border: 1px solid grey;

        text-align: center;

        position: relative;

        }



        .select_country {

        float: left;

        left: 30px;

        top: 30px;

        width: 200px;

        border: 1px solid grey;

        position: relative;

        text-align: center;

        }



        .print {

        border: 1px solid grey;

        text-align: left;

        position: relative;

        }

        </style>

    </head>



    

    

    

    

    

<body>

<div id="container">

    <div class="header">

        <div class="country" >

            </form>

        </div>

        <div class="select_country">

            <form>

                <select>

<?php

    if ($_POST['region'] == '0') {

        foreach($EUcountries as $key => $value){

            echo '<option value="'.$key.'">'.$value.'</option>'; //close your tags!!

}

}

?>

                </select>

            </form>

        </div>

             <div class="print">

I don't see anything glaringly wrong, so:

The only significant issue I can see is in this line:

PHP Code:


echo '<option value="'.$key.'" '.$_POST['region'] == '$key' ? 'selected' : '>'.$value.'</option>';

The problem would manifest itself in the generated HTML. So yes, looking at that would be good.

Hi, thanks for the correction with my post bradgrafelman!

I fixed the issue with the help of my friend.

The issue was that line

echo '<option value="'.$key.'" '.$_POST['region'] == '$key' ? 'selected' : '>'.$value.'</option>';

I had to change it like this:

echo '<option value="'.$key.'" '.(isset($_POST['region']) && $_POST['region'] == $key ? 'selected' :'').' >'.$value.'</option>';

but not before changing the name of my form to something unique rather than it being the same as the name of my <select> tag.

Thanks alot guys!
