Notice: Undefined index: Page in C:\xampp\htdocs\CDMS\proposals.php on line 302

Instead of this:

$Page = $_GET["Page"];
if(!$_GET["Page"])
{
$Page=1;
}
$Prev_Page = $Page-1;
$Next_Page = $Page+1;

Try this:

$Page = $_GET["Page"];

if($Page == 0) $Page = 1;
$Prev_Page = $Page - 1;                     
$Next_Page = $Page + 1;

AndreRet is correct about this query being $Page not $Next_Page:

echo " <a href ='$_SERVER[SCRIPT_NAME]?Page=$Next_Page'>Next>></a> ";

It should be $Page not $Next_Page

for($i=1; $i<=$Num_Pages; $i++){
if($i != $Page){
echo "<a href='$_SERVER[SCRIPT_NAME]?Page=$i'>$i</a> ]";
}else{
echo "<b> $i </b>";
}
}
if(!$Page=$Num_Pages){

echo "<a href ='$_SERVER[SCRIPT_NAME]?Page=$Page'>Total Pages</a>";

}else if($Prev_Page){

echo "<a href='$_SERVER[SCRIPT_NAME]?Page=$Prev_Page'>Prev Page</a>";

}else if ($Next_Page{

echo "<a href='$_SERVER[SCRIPT_NAME]?Page=$Next_Page'>Next Page</a>";
}

@missy_mi

it means that all the data is display..instead of just 4 data per page..
do get what i mean??

Can you post your update code not the results. Right now, I don't know what is wrong with your code because you mention you made some adjustments.

@missy_mi

You have a duplicate of this (it should be one):

$Per_Page = 4; // Per Page

The issue is here:

for($i=1; $i<=$Num_Pages; $i++){
if($i != $Page)
{
echo "[ <a href='$_SERVER[SCRIPT_NAME]?Page=$i'>$i</a> ]";
}
else
{
echo "<b> $i </b>";
}

i dont understand, sir..what seems to be the problem..??

You have a duplicate line 54 and on line 63:

$Per_Page = 4; // Per Page

The issue is here about echo out more than 4 lines:

for($i=1; $i<=$Num_Pages; $i++){
if($i != $Page)
{
echo "[ <a href='$_SERVER[SCRIPT_NAME]?Page=$i'>$i</a> ]";
}
else
{
echo "<b> $i </b>";
}

{
echo "[ <a href='$_SERVER[SCRIPT_NAME]?Page=$i'>$i</a> ]";
}

I don't have db for your code so you have test it out and let me know whether it work or not.

try

if (isset($Page)){
       if (!$Page){
           $Page=1;
       }

       // And so on and so forth :)
    }

In these parts for back, next etc, shouldn't Page be $Page?

echo " <a href ='$_SERVER[SCRIPT_NAME]?Page=$Next_Page'>Next>></a> ";

no changes guys..sAME RESULT..

diafol · Answer 8 · 2012-11-28T23:04:54+00:00

I think it's due to this:

 $Page = $_GET["Page"];

The only index I can see in the code is the above. It means that the get var hasn't been set yet.

$Page = (isset($_GET["Page"])) ? intval($_GET["Page"]) : 1;

That should safely set your page to the integer value of the get variable if it's set or default to 1.

missy_mi 0 Junior Poster in Training · Answer 9 · 2012-11-29T00:35:39+00:00

@diafol & all :

i already change it and there are no more notice that..but, the 1 page shows all the the data i specifically code.. 4 -- $Per_Page = 4; // Per Page ..but it display all.. what do i do??

diafol · Answer 10 · 2012-11-29T00:55:30+00:00

he 1 page shows all the the data i specifically code.. 4 -- $Per_Page = 4; // Per Page ..but it display all.. what do i do??

Sorry, I don't understand

@missy_mi

OK, I'm getting confused too. The issue is that all of the 4 pages appear at once? You want it to display one page at a time?

Can you post your update code so we can see what is the issue?

missy_mi 0 Junior Poster in Training · Answer 12 · 2012-11-29T05:01:56+00:00

okayh...the item displayed should have only 4 line of data..e:g

-harry, 12
-sully, 15
-daniel, 12
-maria, 15
-george, 17

other data should not appear in the first page because i applied :

$Per_Page = 4;

but, the resul i got was :

-harry, 12
-sully, 15
-daniel, 12
-maria, 15
-george, 17
-cullen, 11
-sarah, 14
-henry, 13
-michelle, 17

it means that all the data is display..instead of just 4 data per page..
do get what i mean??
