Please help me Fix this Code to Get content of Tag Name <content:encoded>

I know this is not coding.. However...
How tolerant is PHP from generating a random output from 1000s of entry columns in a mysql database.
I would like to make a script that would potentially pick one of a 1000 results at random.
is this a problem with being ran multiple times?

I'm just searching for some input on a function I saw and wanted someone who could explain to me what this function would mean. As I have the same db structure and was curious specifically to know what sort of values I should have inside of the fields for varcharfield and textfield.


function customfieldinput($fedid,$id,$groupid,$styleid)
{
$query = "SELECT
field.id as getfieldid,
field.is_custom as getiscustom,
field.fullname as getfullname,
customfields.id as getcustomfieldid,
customfields.varcharfield as getvarchar,
customfields.textfield as gettext
FROM
efed_list_fields as field
LEFT JOIN
efed_content_customfields as customfields
ON
(
field.id = customfields.field_id and
customfields.character_id = '$id'
)
WHERE
field.fed_id = '$fedid' and
field.style_id = '$styleid' and
field.group_id = '$groupid' and
field.enabled = '1' and
field.is_custom > '0'
ORDER BY
field.is_custom,field.fullname";
$result = mysql_query ($query); 
while ($row = mysql_fetch_assoc($result))
{
$fieldarray=array('getfieldid','getiscustom','getfullname','getvarchar','gettext','getcustomfieldid');
foreach ($fieldarray as $fieldlabel)
{
if (isset($row[$fieldlabel])) 
{ 
$$fieldlabel=$row[$fieldlabel];
$$fieldlabel=cleanquerydata($$fieldlabel);
}
}

if ((isset($getcustomfieldid)) && ($getcustomfieldid > "0")) { $update = "update"; } else { $update = "new"; }

if ($getiscustom == "1")
{
print "<tr>\n";
print "<td width=120 class=rowheading>".$getfullname.":</td>";
print "<td class=row3><textarea name=\"custom".$getfieldid.$update."\" class=\"textarea490x100\">";
if ((isset($gettext)) && ($gettext != "")) { print $gettext; }
print "</textarea></td>\n";
print "</tr>\n\n";
}
else
{
print "<tr>\n";
print "<td width=120 class=rowheading>".$getfullname.":</td>";
print "<td class=row3><input type=text name=\"custom".$getfieldid.$update."\" class=fieldtext490";
if ((isset($getvarchar)) && ($getvarchar != "")) { print " value=\"".$getvarchar."\""; }
print "></td>\n";
print "</tr>\n\n";
}

if (isset($getcustomfieldid)) { unset ($getcustomfieldid); }
if (isset($getvarchar)) { unset ($getvarchar); }
if (isset($gettext)) { unset ($gettext); }
}
}

how do I pull out two random integers at the same time without ever possibly choosing the same integer twice?

How would I make it so that
for every set of data where a fieldname is 1+ it picks a random one out.
For example
User             Hit
Luke             0
Peter            1
Alex              3
Peter            1

For every value where Hit is 1 or over it selects out of the query results a random username.

i wanted to choose 5 random numbers from 0-20. each number represents an index in an array. is there a way to pick out 5 random items from the array. say if random number generator piked a number 22, the last item in the array is at index 20, it wud then have to go to index 0.

thanks!

here is the database:

its a facebook app

i want that my sql will choose every time random but considerate in the sex parameter.
i mean that if the user is boy i will put it in parameter and boys is num-1 girls-0
and if the user is boy it will run random sql just on the boys
and if its girls so random on the girls


here what i did:
$sql = "SELECT * FROM  pcm ORDER BY RAND() LIMIT 1";

  $Recordset3 = mysql_query($sql) or die(mysql_error());

  $row2 = mysql_fetch_object($Recordset3);

  print_r($row2);


but for some reason i get an error that the database is not selected

maybe i didnt select my database right?

please help tnx....

hello, i am trying to see how i can pick a random number between 1-15 and exclude certain numbers.

so i have a staff list that once a random number is created it inserts it into the staffnumber field.  so the next time i create a random number for a staff, i want to make sure that the random number doesnt select an existing staffnumber.

thanks!

I want to loop through all the values of an array.. but each time, JUST FOR THE LOOP, i want to go through the array values randomly.

How do you suggest I do this?

Hi Guys,

I have a php script to upload a photo to a mysql table. This works great, until someone uploads a file with the same name, then it replaces the old one. Bad times!

So Ive researched it and I have put a timestamp on the filename and it uploads with the correct timestamp in the images folder.

However the data that it uploads to the table is just the original filename, ie it doesnt stamp the filename in the table therefore they dont match...

Any ideas...

<?php 

include('config.php'); 
if (isset($_GET['Ter']) ) { 
$ter = (int) $_GET['Ter']; 
if (isset($_POST['submitted'])) {

//Photo Upload

//This is the directory where images will be saved
$name=time();
$target = "images/"; 
$target = $target .$name. basename( $_FILES['photo']['name']);
//This gets all the other information from the form 
$photo = ($_FILES['photo']['name']);
//Pause Photo Upload


foreach($_POST AS $key => $value) { $_POST[$key] = mysql_real_escape_string($value); } 
$sql= "UPDATE `ter` SET `Ter` =  '{$_POST['Ter']}' , `BranchName` = '{$_POST['BranchName']}' ,  `BranchAddress` =  '{$_POST['BranchAddress']}' ,  `BranchTel` =  '{$_POST['BranchTel']}' , `BranchEmail` =  '{$_POST['BranchEmail']}' , `BranchLink` =  '{$_POST['BranchLink']}' , `Theme` =  '{$_POST['Theme']}' , `LocalInfo` =  '{$_POST['LocalInfo']}' , `BranchInfo` =  '{$_POST['BranchInfo']}' , `photo` =  '{$_FILES['photo']['name']}' WHERE `Ter` = '$ter' "; 

mysql_query($sql) or die(mysql_error()); 


//Unpause Photo Upload
//Writes the photo to the server 
if(move_uploaded_file($_FILES['photo']['tmp_name'], $target))
{
//Tells you if its all ok
echo "<br />The file ". basename( $_FILES['photo']['name']). " has been uploaded. <br />";
}
else {
//Gives and error if its not
echo "";
} //End of Photo Upload

echo (mysql_affected_rows()) ? "<br />Edited Branch.<br />" : "<br />Nothing changed. <br />";  
} 
$row = mysql_fetch_array ( mysql_query("SELECT * FROM `ter` WHERE `Ter` = '$ter' "));
?>

The purpose of this function is to go to the characters table and grab all of the characters that have a statusID of one however I want it to limit it to any ONE of those characters as this is a random image it's going to show and then I want it to have that charactes shortName and then use it to find their spotlight image from inside of the images/spotlight folder. All its showing right now in its spot is the the filename of the image when I call this function.

function spotlight(){

$query = "SELECT * FROM characters WHERE characters.statusID = 1 LIMIT 1";

$result = mysql_query($query);

$row = mysql_fetch_assoc($result);

$labels = array('shortName');
    $img = array();

if($handle = opendir('images/spotlight/')) {

$count = 0;

while (false !== ($file = readdir($handle))) {

if(strlen($file) > 2){

$img[$count] = $file;

$count++;

}

}

}

echo $img[rand(0, (count($img)-1))];
} 

Is there anyway in MySQL you can select a random record in a table?  I normally do this by generating a random number first and then using that number to find a record but was wondering if there is an easier way.  Thanks for any help. 

Hi Guys

I have a code what inserts very simple queries to database, im trying to add a random reference number for each enrty using
$reference = rand(111111111111,999999999999);

but each time I add an entry it gives me the same random number previously generated for previous entry

can you help pleasE?

I need some help working out this MySQL query:   I need it to pull a random quote, that hasn't been used before (that's the 'checked' part of the query), and it needs to find it based on a specific category. I am using this alongside PHP with MySQLI Prepared method.  

SELECT `id`, `word`, `def` FROM `dictionary` AS `r1` JOIN (SELECT (RAND() * (SELECT MAX(`id`) FROM `dictionary`)) AS `id`) AS `r2` WHERE `r1`.`id` >= `r2`.`id` AND `category`=? AND `checked`=0 ORDER BY `r1`.`id` ASC LIMIT 1

  This query yields an error stating that the id column is ambiguous. 

Okay, minor issue, but not sure how to resolve.  I have a form that processes through PHP and has it's fields validated with JS and sends the data to an e-mail address and a database. It works fine, but there are random times where a submitted entry will show up blank in the e-mail and not be in the database at all, any ideas on what might be causing this? Thanks.
