PHP - Display Selected After Failed Submit

I have a problem that is particular to the FF and Safari browsers.  I do not see the problem in IE.

Again, I am very new to php programming - no formal training - just a hacker.

I have a web page that presents a form with a results table and a SUBMIT button.  Each time the button is selected I want to present one of two different tables of results. 

Everything works fine the first time I hit the SUBMIT button.  The page updates and shows the second table.

But on the next SUBMIT the script that swaps things around is executed twice in FF and Safari vs. one time like in EI.

This results in the same result table being displayed over and over vs. the two switching back and forth.

Any idea what could be going wrong in these two browsers?

Here's my swap script:

Code: [Select]
<?php
session_start();
// This script reverses the coin flip to see what would happen the other way
if ($_SESSION['Coin_Flip'] == "heads") { //switch to tails
  $_SESSION['Coin_Flip'] = "tails";
  include ('tails_algo.php');
} elseif ($_SESSION['Coin_Flip'] == "tails") {
  $_SESSION['Coin_Flip'] = "heads";
  include ('heads_algo.php');
}
include ('kind-comp_result.php');
?>

here is the code

Code: [Select]

<label for="rank">Font</label>
<select class="element select medium" id="fonts" onchange="<?php echo 'selected'; ?>" name="fonts">
<option value="Arial" selected="selected">Arial</option>
<option value="times" selected="selected">Times New Roman</option>
</select>

It is supposed to echo the value selected but it does nothing any ideas regarding what i should do?
Also what i really want to do is create a cookie which will contain the selected value and then use this value of the cookie later. But I cant even manage to echo the values so thought it would be better to first learn how to echo and then try to create a cookie out of it

Hey! I am trying to get a database table of users but am running into the error:

Warning: file_get_contents(http://protege-ontology-editor-knowledge-acquisition-system.136.n4.nabble.com/template/NamlServlet.jtp?macro=user_nodes&amp;user=68583) [function.file-get-contents]: failed to open stream: HTTP request failed!

I have looked it up and it may be a security thing...The urls I am getting are http://protege-ontology-editor-knowledge-acquisition-system.136.n4.nabble.com/template/NamlServlet.jtp?macro=user_nodes&user=68583 but the error adds an nodes&amp; part that screws it up. Any way around this?

I am trying to figure how to code around this. I have a DOM scraper function that pulls urls from my database, opens the page, scrapes the data, and then moves onto the next URL to scrape. my issue is that if the page fails to load the script bombs and I have to restart it again. Trying to figure out how if the Code: [Select]
$html->find('div[class="itemHeader address"]') as $div fails to open the page it just skips the DOM inspection.

Here is my error...

Failed to open stream: HTTP Request failed.

Here is where I am at with my script....

Code: [Select]
mysql_select_db("scraped") or die(mysql_error());
$result = mysql_query("SELECT PKEY, URL, HASSCRAPED, SHOULDSCRAPE FROM CRAWLED WHERE SHOULDSCRAPE ='1' AND HASSCRAPED = '0'") or die(mysql_error()); 

while($row = mysql_fetch_array( $result )) {
mysql_query("UPDATE CRAWLED SET CRAWLED.HASSCRAPED =  '1' WHERE CRAWLED.URL = '" . $row['URL'] . "'");
$html = file_get_html($row['URL']);
foreach($html->find('div[class="itemHeader address"]') as $div) {
foreach($div->find('a') as $element){
$CleanData = CleanData($element->innertext);
if (strlen($CleanData[0]) > 5){
    mysql_query("INSERT INTO SCRAPED (ADDR1, CITY, STATE, ZIP, URL, DATE) VALUES ('" . $CleanData[0] . "','" . $CleanData[1] . "','" . $CleanData[2] . "','" . $CleanData[3] . "','". $row['URL'] . "','". date( 'Y-m-d H:i:s ' ) ."')");
        }
}
}

$html->clear();
unset($html);
unset($CleanData);
}

function CleanData($data) {
  $NewData = trim($data);
  $NewData = str_replace("<em>", "", $NewData);
  $AddrCityStateZip = explode("</em>",$NewData);
  $CityStateZip = explode(",",$AddrCityStateZip[1]);
  $StateZip = explode(' ',$CityStateZip[1]);
  $NewDataArray = array ($AddrCityStateZip[0], $CityStateZip[0], $StateZip[1], $StateZip[2]);
  return $NewDataArray;
  unset($NewData);
  unset($AddrCityStateZip);
  unset($CityStateZip);
  unset($StateZip);
