PHP - Converting The "&" Symbol Into Special Characters In Url

Can someone please help me with an array problem i can not figure out.

I need the array to be numbered from 1 to how ever many fields that are needed in the form and have a mysql field name and the title of the field also in the array.

1, "mysql_field_name", "Title of form field"
2, "", ""

and so on

then the form will be shown based on the array.

I have the following draft code which I am working with.

any suggestions on how i may do this array ?

Code: [Select]
<?php
$options = array(
'1'=> array('fieldtext'=>'option1', 'mysqlfield'=>'option1'),
'2'=> array('fieldtext'=>'option2', 'mysqlfield'=>'option2'),
'3'=> array('fieldtext'=>'option3', 'mysqlfield'=>'option3'),
'4'=> array('fieldtext'=>'option4', 'mysqlfield'=>'option4'),
);


// $options = array(1 => "option1", "option2", "option3", "option4");

// the line above works but i want to include the name of the mysql field as well.

$userid = 1;

?>
<div style="align: center; margin: 12px; font-family:Tahoma;">
<br><br><?php
if ($_POST['Update'] != "Update") { // check if form submitted yet, if not get data from mysql.
$res = db_query("SELECT * FROM `users` WHERE `userid` = '" . $userid . "'");
foreach($options as $key => $value) { $_POST[$key] = mysql_result($res, 0, $value); }
$ok_to_update = "no";
} elseif ($_POST['Update'] == "Update") { // check if form submitted yet, if so get POST data.
// error checking
// foreach($options as $key => $value) {
// $_POST[$i] = "";
// }
$ok_to_update = "yes";
}

if ($_POST['Update'] == "Update" && $ok_to_update == "yes") {
// $res = db_query("INSERT INTO `users` () VALUES ()"); // add user details to database.
?><p><br><br><br>Thank you for updating</p><?php
} else {
?><form name="form1" method="post" action="">
<?php foreach($options as $key => $value) {
?><p><?php echo($value); ?>:&nbsp;<input type="text" name="<?php echo($key); ?>" value="<?php echo($_POST[$key]);?>"></p>
<?php } ?>
<input name="Update" type="submit" value="Update">
</form>
<?php } ?>
</div>

Hi all,


I've been running a basic contact us form using a textarea for users to send us enquiries for a few months now. We have a few foreign users that use special accented characters like umlaut etc... Which are common to lots of languages other than english. When the php script processes the data and sends it in a html based email it screws up the symbols and sends a load of rubbish where they should be.

I have been trying out a few variations of script but cannot get any to display correctly.

Old script:

function previous_request_value($str) {
if (isset($_REQUEST[$str]) )
return $_REQUEST[$str];
else
return '';
}

function cndstrips($str) {
if (get_magic_quotes_gpc())
return stripslashes($str);
else
return $str;
}

$visitor_email=cndstrips(trim(previous_request_value('visitor_email')));
$visitor_name=cndstrips(trim(previous_request_value('visitor_name')));
$visitor_companyname=cndstrips(trim(previous_request_value('visitor_companyname')));
$message_body=cndstrips(trim(previous_request_value('message_body')));
$message_telephone=cndstrips(trim(previous_request_value('message_telephone')));
$msg_subject=cndstrips(trim(previous_request_value('msg_subject')));


Current Version (My attempt at editing the code to convert specialchars still doesnt work correctly):


function previous_request_value($str) {
if (isset($_REQUEST[$str]) )
return $_REQUEST[$str];
else
return '';
}

function cndstrips($str) {
if (get_magic_quotes_gpc()) {                           
$str = htmlspecialchars(stripslashes($str), ENT_QUOTES);
} else {
$str = htmlspecialchars($str, ENT_QUOTES);
}
preg_replace('/&(?![A-Za-z0-9#]{1,7};)/','&amp;',$str);
return $str;
}

$visitor_email=cndstrips(trim(previous_request_value('visitor_email')));
$visitor_name=cndstrips(trim(previous_request_value('visitor_name')));
$visitor_companyname=cndstrips(trim(previous_request_value('visitor_companyname')));
$message_body=cndstrips(trim(previous_request_value('message_body')));
$message_telephone=cndstrips(trim(previous_request_value('message_telephone')));
$msg_subject=cndstrips(trim(previous_request_value('msg_subject')));


Any ideas where i'm going wrong?

Plus another slightly annoying feature is if a user enters html entities as &amp; instead of just &, it double encodes it to &amp;amp; I have tried to use htmlspecialchars_decode first but it crashes the whole script.

I'd appreciate any help available. Thanks.

Hi,

bit stuck on how to find and replace "<" and ">" with "&lt;" and  "&gt;". I basically have a database record that outputs to screen and I need the code in the <code> tags to be rendered to the screen. I therefore need it to go through the whole array variable from the db and change the symbols just inside the code tags. Please be aware that the code tags might happen more than once

here's an example below

Code: [Select]
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
<h1>hello</h1>
</code>
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
<h1>hello</h1>
</code>

the desired output would be:

<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
&lt;h1&gt;hello&lt;/h1
</code>
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
&lt;h1&gt;hello&lt;/h1
</code>

help on this would be great

Cheers

Rob

Code: [Select]
function time_ago($timestamp)
{
//$months = array("Jan" => 31, "Feb" => 28, "Mar" => 31, "Apr" => 30, "May" => 31, "Jun" => 30, "Jul" => 31, "Aug" => 31, "Sept" => 30, "Oct" => 31, "Nov" => 30, "Dec" => 31);
$curr_time = time();
$time_ago = $curr_time - $timestamp;
if($time_ago < 60) // seconds
{
$ext = $time_ago . " seconds ago..";
}
else
{
if($time_ago >= 60) // minutes
{
$time = floor($time_ago / 60);
$seconds_remainder = $time_ago % 60;
$ext = $time . " minutes " . $seconds_remainder . " seconds ago..";

if($time >= 60) // hours
{
$hours = floor($time / 60);
$minutes = $time % 60;
$ext = $hours . " hours " . $minutes . " minutes ago..";
if($hours >= 24) // days
{
$days = floor($hours / 24);
$day_hours = $hours % 24;
$ext = $days . " days " . $day_hours . " hours ago ..";
}
}
}
}
return $ext;
}

It seems to work fine (was going to tackle Months but haven't done it yet), but anyway is there a better way to do this? I'm guessing there is as I wrote this up rather fast and I'm not that great with date math. Any suggestions are appreciated (besides maybe using ternaries which I'm working on atm).

Code: [Select]
function time_ago($timestamp)
{
   //$months = array("Jan" => 31, "Feb" => 28, "Mar" => 31, "Apr" => 30, "May" => 31, "Jun" => 30, "Jul" => 31, "Aug" => 31, "Sept" => 30, "Oct" => 31, "Nov" => 30, "Dec" => 31);
   $curr_time = time();
   $time_ago = $curr_time - $timestamp;
   if($time_ago < 60) // seconds
   {
      $ext = $time_ago . " seconds ago..";
   }
   else
   {
      if($time_ago >= 60) // minutes
      {
         $time = floor($time_ago / 60);
         $seconds_remainder = $time_ago % 60;
         $ext = $time . " minutes " . $seconds_remainder . " seconds ago..";
         
         if($time >= 60) // hours
         {
            $hours = floor($time / 60);
            $minutes = $time % 60;
            $ext = $hours . " hours " . $minutes . " minutes ago..";
            if($hours >= 24) // days
            {
               $days = floor($hours / 24);
               $day_hours = $hours % 24;
               $ext = $days . " days " . $day_hours . " hours ago ..";
            }
         }
      }
   }
   return $ext;
}

Is there a cleaner approach to this?
