    [SOLVED] errors when echoing a variable

include "idea/resulttemplate.php";

echo "\n"; 

} 

   



?>

     

    And then, in other.php, remove the echo.

    [SOLVED] Log latest searches

    in PHP Coding Help

    Posted

    I'll show you how to make it with a MySQL database =)

     

    Create a new table, named searches.

     

    Inside this table, add 2 fields.

     

    id | int | 30 | primary key | auto increacement

    name | varchar | 65

    You should make sure that you make a variable for the thing they search for. In this case, I'll name the variable $searched_for

    Now, when a user presses the search button, run the following query.

     

    mysql_query("INSERT INTO `searches`(`name`) VALUES('{$searched_for}')") or die(mysql_error());

     

    Now when you want to show the 10 latest searches, you can do a for loop, like this:

     

    $select=mysql_query("SELECT * FROM `searches` ORDER BY `id` DESC") or die(mysql_error());
for($i=1;$i <= 10;$i++)
{
$row=mysql_fetch_array($select);
echo $row['name'];
}

     

    I think this should work. Not tested, but try it, and tell me if any errors occurs =)

    [SOLVED] Paging

    if $result['items'] is the news items, you can use the count to count them by doing the following.

    If not, I'd like to know how you get the number of search results, so that I can think clearly.

     

    $items=count($result['items']);

     

    Now to decide how many pages you want, you divide the $items, with the number of results you want on every page, in this case - 10.

    Like this.

     

    $pages=$items/10;

     

    There you got the max pages.

     

    Is this what you need?

    $result = mysql_query("SELECT userpass FROM Users WHERE usname = '{$_SESSION['usname']}'") or die(mysql_error());

     

    if you try to echo the variable $results, I think that you wont get anything =)

    Am I right?

     

    If I am, try doing it like this instead:

     

    $result = mysql_query("SELECT userpass FROM Users WHERE usname = '{$_SESSION['usname']}'") or die(mysql_error()); 
$row=mysql_fetch_assoc($result);

     

    And then when you get to the if statement, change it to this:

     

    if ($salt_passo != $row['userpass']) 
{
   echo "Your old password was entered incorrectly";
}

    Try this =)

session_start();

$opass = $_POST["opass"];
$npass = $_POST["npass"];
$npass1 = $_POST["npass1"];

$salt_passo = md5($opass.$salt);
$salt_passn = md5($npass.$salt);
$result = mysql_query("SELECT userpass FROM Users WHERE usname = '{$_SESSION['usname']}'") or die(mysql_error()); 

if(isset($_SESSION['usname']))
{

if ($salt_passo != $result) 
{
echo "Your old password was entered incorrectly";
}
elseif ($salt_passo != $salt_passn)
{
echo "The two new password didn't match";
} 
else 
{
mysql_query("UPDATE `Users` SET `userpass`='{$salt_passn}' WHERE `usname` = '{$_SESSION['usname']}'") or die("Error: ".mysql_error());
}
}
else
{
echo '<meta http-equiv="refresh" content="2;url=index.php">';
}

?>

     

    I think you've been programming another language for a while, and newly started PHP?

     

    Instead of doing the following

     

    else{
if{

    And forget to close both of them

    Try using the

     

    elseif()
{}

    Gmail like page updation(refresh)

    in PHP Coding Help

    Posted

    The following code is normal HTML DOM:

     

    <div id="test">
Lalalalalalala
</div>
<div>
<input type="button" value="click here" onclick="getElementById('test').innerHTML+='testtesttest'" />
</div>

     

    What it does is, when the button is pressed, it adds the text "testtesttest" after the "lalalalalala.."

     

    You can do the same thing but with ajax.

     

    When the timer expires, run a PHP script, and make sure you add the following code in the end of the function:

     

    getElementById('TheDivId').innerHTML+=xmlhttp.responseText;

     

    Inside the PHP script, check if there are any new news. If there is any new news item, make sure that you echo it.

     

    Hope this isn't confusing. You'll need to define the xmlhttp before you can use this function.

    Here's a link that might help.

    without a ajax refresh -

     

    According to what I know, the only way to get something from the database, or from the server itself, without refreshing the page, is by using AJAX.

     

    I don't think there is any other way.

     

    Edit:

     

    What you'll have to do is set a JavaScript timer, and every time the timer reaches 0, run an AJAX function, and reset the timer. That will set it in a loop, and the AJAX function will get what you need from the database and insert it into the news div.

    Updating DB info

    in PHP Coding Help

    Posted

    This is simple math =)

     

    Let's say I have the variable 10.

    I'd write it like this

     

    $num=10;

     

    Now I want to increase the value of that variable by 25%.

     

    All I need to do is multiply the variable with 1.25, which is +25%.

     

    The code would look like this:

    $num=10;
$num*=1.25;
echo $num;

     

    The output would be 12.5, because 0.25(25%) out of 10 is 2.5, and + the 1 (100%), it becomes 12.5.

     

    Hope this helped =)

    Have you tried the link that corbin sent you?

     

    Because you have the answer there.

     

    Try using the update statement:

     

    Let's say I have selected the total views on my page, and then I want to echo it.

    I'd do it like this:

     

    $sel=mysql_query("SELECT * FROM `statistics` WHERE `id`=1") OR die(mysql_error());
$row=mysql_fetch_array($sel);
echo $row['views'];

     

    Now everytime a user visits the page, I want to increase the 

    $row['views']

    with one.

     

    I'd need to add the following rows.

     

    $row['views']+=1;
mysql_query("UPDATE `statistics` SET views='{$row['views']}' WHERE `id`=1") OR die(mysql_error());

     

    The first row, 

    $row['views']+=1;

    , increases the value of "views" by one.

     

    The second row, Updates the value of "views" inside the database, where the ID is one (of course you can change that).

     

    Now the final code looks like this:

     

    <?php
include("config.php");
$sel=mysql_query("SELECT * FROM `statistics` WHERE `id`=1") OR die(mysql_error());
$row=mysql_fetch_array($sel);

$row['views']+=1;
mysql_query("UPDATE `statistics` SET views='{$row['views']}' WHERE `id`=1") OR die(mysql_error());

echo $row['views'];
?>

     

    Check this site for more information about the UPDATE statement:

    You'll have to find a way to find out how many pages there are, and then do the following.

     

    Create a variable that contains the maximum number of pages.

     

    For example:

    $max_pages=10 //In this case, but you might want to check by looking in a database or something.

     

    Then change the following code:

    if ($start > 1 && <= $max_pages) { // because 1 is the first page
//Echo the current page, and add a "next" and "previous" button.
echo "Page #$start <br/>";
echo "<a href=\"?page=$past\">Previous</a> |";
echo " <a href=\"?page=$next\">Next</a> ";
}

     

    And add the following code:

    if ($start <= $max_pages)
{
echo "<a href=\"?page=$past\">Previous</a>";
}

     

     

    And about the search thing, you just have to add it =)

    Try learning from this =)

     

    <?php

//if the page is not set, set it to 1
if(!$_GET['page'])
$_GET['page']=1;

//ser the variable start to the current page.
$start = $_GET['page'];

$perpage = 1;   
$next = $start + $perpage;
$past = $start - $perpage;

//If the current page is less than or equal to 1 ($perpage) 
if ($start <= $perpage) {
//Echo the current page, and add a "next" button.
echo "Page #$start <br/>";
echo "<a href=\"?page=$next\">Next</a>";
}
//If the current page is bigger than one
if ($start > 1) { // because 1 is the first page
//Echo the current page, and add a "next" and "previous" button.
echo "Page #$start <br/>";
echo "<a href=\"?page=$past\">Previous</a> |";
echo " <a href=\"?page=$next\">Next</a> ";
