noob php img question

mpinter09

Hey all,

My first php code is quite frustrating. I can't figure out why it won't work. All I'm trying to do is output an img based on a selection from a dropdown menu. Can anyone give some feedback or advice? Thank you.

<html>

<body>

<option value="Choose County">[Choose Your County]</option>
<option value="Alameda">Alameda</option>
<option value="Alpine">Alpine</option>

</select>

</form>

<?php

$countylist = $_GET['countylist'];

if ($countylist=="Alameda")
{
echo "<img src=‘http://upload.wikimedia.org/wikipedia/commons/thumb/e/e9/California_county_map%28Alameda_County_highlighted%29.svg/500px-California_county_map%28Alameda_County_highlighted%29.svg.png

’ alt=“Alameda County” height=“42” width=“42” />";
}
elseif ($countylist=="Alpine")
{
echo "<img src=‘http://upload.wikimedia.org/wikipedia/commons/thumb/0/08/California_county_map%28Alpine_County_highlighted%29.svg/500px-California_county_map%28Alpine_County_highlighted%29.svg.png

’ alt=“Alpine County” height=“42” width=“42” />";
}

</body>

</html>

In your form change the action to action='', No need for address as your posting to the same page. It works once you change that. And why not use POST instead of GET. POST data can't be seen by the user where as GET is sent in the URL. Just change GET to POST and jobs done.

Use html, php and code tags when posting code.
The action attribute takes a URI, not a local file path, since the user's browser wouldn't know where that is (it certainly isn't on their computer).

Because the HTML spec (at least pre 5, and I doubt it's changed) specified usage recommendations for GET and POST requests. GET requests are to be used for requests that are idempotent, i.e. they will always provide the same result after the first time it's issued. If sending the form multiple times would mean storing new data on each request, then it should be a POST request. In this case however, a URL is created which will always yield the same result, and thus that page can even be bookmarked, which wouldn't be possible if a POST request was used. Moreover, the POST request would have to always be berformed, whereas the GET request might not have to (depending on cache headers).
