Hi guys,

I would like to know on  How to alternate table row colors in Php Mysql result? CSS or Html?

Thanks

Code: [Select]
<?  $result = mysql_query("SELECT * FROM tbl_sta WHERE fiesta_date > '$now' ORDER BY sta_date LIMIT 5");
  echo "<table id='table1' cellspacing='1' cellpadding='3'>
  <tr>
  <th>Upcoming Fiesta</th>
  </tr>";
 
  while($row = mysql_fetch_array($result)){
             
  $date = date("l, F j ",strtotime($row["sta_date"]));

  echo "<tr>";
  echo "<td><a href='fiestasd.php' style='font-size:12px;font-weight:bold;'>" . $row['fiesta_brgy'] . " " . $row['fiesta_town'] . "</a> <br />  $date  </td>";

Thank you.. more power phpfreaks!

Hi all,

    I am still learning all the variations of code commonly used with sites. I have one particular issue of which I am having trouble locating an answer or returning a proper result.  I want to be able to use one page to query a distinct date, say 1-1-11 and the results return with the other columns matching this date and separating the time to be displayed for the entry row. So it would look something like this in the results.

Acct: Tester User: John.Smith Time: 1:30 PM

Currently there are 4 columns to the table, ID, Acct, Logintime, User.  I have tried splitting this off the table but that fails out, unless someone knows an insert command to enter date and time individually. This would make it much easier for my purposes as well.

Below is one of the many codes I have tried for this from examples.

<?php
$con = mysql_connect("localhost","gram","compassion");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("tester", $con);

$result = mysql_query("SELECT * FROM test_history");

echo "<table border='1'>
<tr>
<th>Date:</th>
<th>Time:</th>
</tr>";

while($row = mysql_fetch_array($result))
  (explode(" ",$row['logintime']));
  echo $row[0];
  echo $row[1];

  {
  echo "<tr>";
  echo "<td>" . $row[0] . "</td>";
  echo "<td>" . $row[1] . "</td>";
  echo "</tr>";
  }
echo "</table>";

mysql_close($con);
?>


I know I am newb but I am a fast learner if I can merely get some points in the right direction.

Without using FFMPEG that is, since my host refuses to allow it. I really don't want to change hosts just for this one thing, I'm happy otherwise, but I need this work.

I just need to grab a frame from a video when the user uploads the video. I can't use FFMPEG like I said, but I saw a suggestion someone had that said "have PHP open the video in fullscreen and take a screencap". That would work perfectly, I just have not a CLUE how to do it.

Does anyone have experience doing this? I just want it to grab a screenshot and have it saved as a jpg with the same filename as the video, for obvious reasons...call the video player and pass it the filename with a .jpg attached for the screenshot param.

Any help is appreciated! Thanks.

Hi There!
Hopefully someone can help. I'm looking for some php script that allows me to display mysql table data in alternating row colors (eg 5 columns and  500 rows). I would also like to add pagination and limit number of rows displayed at a time to e.g. 50. If possible I'd like to be able to sort asc/desc using titles(links) at the top of the displayed data. Hopefully someone may have a script like this that also shows the mysql connection code (sample host, pass, user etc...) - a working php file so to speak that I can edit.
Would really appreciate the help. If you could recommend some software or a wizard that could generate the php code for me I would really appreciate it too!

THANKS!

Can anyone provide a snip of code that I could insert into the "coupon code" field on a formmail form which has the following effect:

on submit form, user goes to the normal payment page (this is already implemented)
if coupon code field is filled out with correct code, user is taken to alternate payment page on form submit.

Either this or another approach which has the same result is OK. I am a novice coder working in a wysiwyg - I don't REALLY know php at all - I just need a snip I can insert and a clear instruction.

Thanks so much for any help.

Hello all, I have some piece of code that is nested like this


$variable = 'This is a global argument';
function parentFunction($variable) {
function childFunction() {
echo 'Argument of the parent function is '.$GLOBALS['variable'];
}
childFunction();
}
parentFunction(5);


What I want to know is - Is there a way to access a variable from the parent function without passing arguments to the child function? (Something like how classes have parent::?). I don't want to use $GLOBALS because it might cause some variable collision, and I didn't want to pass arguments because incase I decide to change the arguments in the parent function I'd have to do it in the child function aswell. From my searching around in the Internet it seems like this is not possible, but if theres a slight chance that there might be something out there, i'm willing to give it a shot .

Thanks in advance

Question 1) Is the only and proper way to call a parent function "parent::function()"?  Are there other/better ways from within a child function?

Question 2) What are the deciding factors for when to make a function or attribute static?  How do you make that decision?  Assuming 5.3...

Thanks.

I need to call usort from a class function, and I'm puzzled about how to define the comparison function.

I've tried to define the comparison function in the same class, but I can't get usort to call it. I found one hint that it will work if I make the comparison function static, but I tried that, and it didn't work for me.

If I define the comparison function outside the class, it won't have access to object properties that it needs to operate.

The only solution I can think of is to define the comparison function outside the class and put the object properties it needs in globals. Is there a cleaner way to do this?

I have this function completely written in my class file that I am working on.  The point to this function is to be able to check the login of a user or administrator for either of the control panels associated with my site.

It will check the session intime as well as the page / module referenced.  Once it passes all those checks, it will check and ensure the emailaddress/password stored in the current session still holds true and the account is still active...  if the account is still active it will update the lastActivity as well as update all of the session variables with what is currently in the database.

What I am looking for is basically a look at the function, see if it looks good..  If there is any part to it that could create security holes for the site just off the login function itself...

Usage: $q->validUser($_SESSION['user'], $_mod);

<?php
 function validUser($sess, $p) {

if ($sess['inTime'] == '' && $p != 'login' && $p != 'logout') {
session_destroy();
$login = '0';
$_int = '';
return $login;
} else if ($sess['inTime'] < time()-3600 && $p != 'login') {
$sess['inTime'] = '';
session_destroy();
$this->check_login($sess, $p);
} else {
$this->user = $sess['emailAddress'];
$this->pass = $sess['password'];

$login = $this->sql_query("SELECT * FROM users WHERE emailAddress = '".$this->user."' AND password = '".$this->pass."' 
   AND status = '1' LIMIT '1'");
if ($login = $this->sql_numrows($login) < 1) {
$sess['inTime'] == '';
session_destroy();
$login = '0';
} else {
// logged in, lets update the database for last_activity AND the session.

$this->sql_query("UDATE users SET lastActivity = '".now()."' WHERE
  emailAddress = '".$this->user."'");
$login = $this->sql_query("SELECT * FROM users WHERE emailAddress = '".$this->user."' AND password = '".$this->pass."' 
       AND status = '1' LIMIT '1'");
$login = mysql_fetch_assoc($login);
foreach ($login as $key => $value)
{ 
$sess[$key] = $value;
}
$sess['inTime'] = time();
$login = '1';
}
return $login;
}
}

?>

That is the main function, sql_query and sql_numrows is:

<?php
function sql_query($query = "", $transaction = FALSE) {
unset($this->query_result);

if ($query != "") {
$this->num_queries++;
if ($transation == BEGIN_TRANSACTION && !$this->in_transation) {
$result = mysql_query("BEGIN", $this->db_connect_id);
if (!$result) {
return false;
}
$this->in_transaction = TRUE;
}

$this->query_result = mysql_query($query, $this->db_connect_id);
} else {
if ($transaction == END_TRANSACTION && $this->in_transaction ) {
$result = mysql_query("COMMIT", $this->db_connect_id);
}
}
if ($this->query_result) {
unset($this->row[$this->query_result]);
unset($this->rowset[$this->query_result]);

if ($transaction == END_TRANSACTION && $this->in_transaction ) {
$this->in_transaction = FALSE;
if (!mysql_query("COMMIT", $this->db_connect_id)) {
mysql_query("ROLLBACK", $this->db_connect_id);
return false;
}
}
return $this->query_result;
} else {
if ($this->in_transaction ) {
mysql_query("ROLLBACK", $this->db_connect_id);
$this->in_transaction = FALSE;
}
return false;
}
}

function sql_numrows($query_id = 0) {
if(!$query_id) {
$query_id = $this->query_result;
}
return ($query_id) ? mysql_num_rows($query_id) : false;
} ?>

Any insight that can help to benefit these functions would be appreciated.

I want to define a function instead of repeating query in all my php pages. I call a function by passing an $id value and from that function i have to get all the info related to that id, like name, description and uom.    I am trying to do this, but i dont know how to get these values seperately.   here is my function  

function items($item_id)
{
$details = array(); 
$result = mysql_query("select item_id, name, uom, description from items where item_id=".$item_id."") or die (mysql_error());
while($row = mysql_fetch_array($result))
{
$details[] = array((stripslashes($row['name'])), (stripslashes($row['uom'])), (stripslashes($row['description'])));
}
return $details;
}

and i call my function like this

$info = items($id);

Can somebody guide me in this    

When I put this chunk of code into it's own function:


function fetch_all ($dbc, $query) {

include ('knuffix_list_func.php');

pagination_start ($dbc, $query);

$offset = $pag_array[0];

$rows_per_page = $pag_array[1];

$query = $query . " LIMIT $offset, $rows_per_page";

echo "test query: " . $query;

knuffix_list ($query, $dbc);

pagination_end ($pag_array);
}


And when I echo out the query as you can see in the example, then I notice that the variables $offset and $rows_per_page never get appended.
I set the variable $pag_array to a global inside the function pagination_start(). It usually works when I DON'T wrap a function around this chunk of code, but if I do wrap a function around everything then the global suddenly won't work anymore.

Btw, this also won't work if I wrap a function around the function DECLARATIONS.

Any ideas, how I could make it work?

Hi all, I want to call a javascript function from a php function like this:

        public function Buscar()
        {
            $HoraInicio = $_POST['edtHoraInicio'];
            $HoraFin = $_POST['edtHoraFin'];
            $FechaInicio = $_POST['edtFec1'];
            $FechaFin = $_POST['edtFec2'];

            $FechaMax = $FechaFin." ".$HoraFin.":00";
            $FechaMin = $FechaInicio." ".$HoraInicio.":00";

            $_GET["FechaMax"] = $FechaMax;
            $_GET["FechaMin"] = $FechaMin;

            echo $FechaMin;

            echo "<script language=javascript>alert('Hi.')</script>";
           
        }

but the function Buscar never show the alert but shows the $FechaMin

I hopu u guys can help me out with this probem

Thanks,

Siddhartha

I've followed the PHP Freaks pagination tutorial which you can find here.

And I also got it to work, the only problem is that the script won't work when I use the query outside of the function.

// find total pages -> ceil for rounding up
$total_pages = ceil($num_rows / $rows_per_page);

As you can see above, the script will only work if I put the query right below the $offset variable and above the $data variable.

I put the test echo above the query to see how the query looks like when I induce the query from the outside through the function parenthesis into the function, and this is what I get printed out:


test SELECT * FROM con, user WHERE con.user_id = user.user_id ORDER BY contributed_date DESC LIMIT ,


Obviously the $offset and the $rows_per_page variables are not set, when I induce the query from the outside into the function.

So in that sense my question is:

How can I induce the query from the outside into the function SO THAT the $offset and the $rows_per_page variables are set as well and NOT empty?


p.s.

I need the query outside of the function because I'm using a sort by category functionality.
