PHP - If Statement To Overwrite An Image.

Hi,

I have a page where a user can change his password

what i want to acheive is a way of checking the database if the text the user has entered in the textboxes already exist in the db, and if it does exist change a certain part.

for example the user goes to the address, types in the email, user name and password twice.  if the username and email match in the db i would like the password to write over the old password that was in the db.

i keep confusing myself when i think i know what im doing but i keep stumbling.

i know this sounds a bit confusing so please ask if you need more understanding.

so far ive got:

Code: [Select]
    <?php
$n=$_POST['uname'];
$e=$_POST['email'];

if( $_POST['submitted'] == 'yes' ) {
     if( $_POST['pass_1'] != $_POST['pass_2'] ) {
          // fields don't match, so do something to indicate the error . . .
  
  echo '<p>Passwords Do Not Match</p>';
     }
 // connect to the db
 include('config.php');
 $query="select * from user where uname='$n' and email='$e'";
 $result=mysql_query($query);
 
}
?>
<form action="" method="post">
<input type="text" name="uname" id="uname" size="30">
<input type="text" name="email" id="email" size="30">
<input type="password" name="pass_1" />
<input type="password" name="pass_2" />
<input type="hidden" name="submitted" value ="yes" />
<input type="submit" name="submit" value="Change Password" />
</form>
just by looking at my code again i think its not right at all, the first php bit is only checking the password textboxes. i think i need to remove my email and username out of that form and put them in another. am i right?  sorry im not that good at php or mysql

thanks in advance and sorry for such a long read

does anyone know how to do an if statement in the middle of a gd image so that if a dropdown box is selected it draws different lines...

Code: [Select]
  <label for="height"></label>
  <select name="height" id="height">
    <option value="2.4">2.4</option>
    <option value="2.7">2.7</option>

$y2=$_GET['y2'];
$im = @ImageCreate (800, 600)
or die ("Cannot Initialize new GD image stream");
$background_color = ImageColorAllocate ($im, 255, 255, 255);

I am still a novice, but I am working on an idea.   I have a table with a field: judges_ccpadv that contains only 3 possible characters = B, R, or N   My desire is to display a simple little icon for any of those 3 characters.   I tried: if ($data['judges_ccpadv'] = "B") {
        echo "<img src='images/b.png'>\n";
}
if ($data['judges_ccpadv'] = "R") {
        echo "<img src='images/r.png'>\n";
}
if ($data['judges_ccpadv'] = "N") {
        echo "<img src='images/n.png'>\n";
}   The output is any image that is not in the if statement. So if "B" is in field, r.png and n.png are both displayed.   What am I doing wrong here? Assistance is greatly appreciated.   Thanks!
 

Hi,   I have the following script which displays a banner image based on a cookie. It also displays a banner if there is no cookie. What I would like to do is to display the banners based on cookies, but instead of displaying the "no-cookie.gif" image, I want to insert some HTML content.   What would be the best way to do this?    

$( document ).ready(function() {

    var acode = getVar('agent');

    if (code) SetCookie("code", code, 1);

    else

        code = ReadCookie("code");

    

    var imgsrc = "images/" + code + ".gif";

    var img = new Image();

    

    img.onerror = function (evt) {

          document.getElementById("headimg").src = "images/no-cookie.gif";

      }

    

    img.onload = function (evt) {

          document.getElementById("headimg").src = imgsrc;

        

      }

   

    

});

  Thanks!

I can log-in, and get to the page with the two links on it. However, once I click one of the links it falls back to the log-in page, and it ends up being a never ending loop.

It's doing this:
Log-In --> Page with links ---> Log-In page again

Should be doing this:
Log-In --> Page with links --> Add Product page or View Products page

I can never get into the the actual sub page.

Just to be clear, the address bar actually shows product=add or product=view, but it still shows the log-in page.

Hello Everyone,
I have to change the if statements to a switch statement, in this game. Can anyone help? Thanks.

var checkKeyPressed = function (e) {
// Press key A or key D to make dog run to the left or right
// The running speed is specified by the step variable, 10 by default.
// If you replace 10 with a larger integer, the dog will run faster.

    //press A, dog runs left
    if (e.keyCode == "65") {
        if (prex[0] > 5) {
            prex[0] = prex[0] - step;
        }
    }
    //press D, dog runs right
    if (e.keyCode == "68") {
        if (prex[0] < right) {
            prex[0] = prex[0] + step;
        }
    }
};

I need help with my if/else statement.

Code: [Select]

$result = mysql_query($query) or die(mysql_error());

echo "<table>";

while($row = mysql_fetch_array($result))

  {
     echo "<tr>
            <td rowspan='3' width='155' class='show_image'>
             <a href='". $site ."show_page.php?show_id=". $row['show_id'] ."'>
             <img src='". $site ."images/". $row['show_graphic1'] ."' height='150' width='150'></img></a>
        </td>
            <td class='show_name'>
             <h1>";
              if ($row['host'] == "")
                {
                 echo $row['show_name']" with " $row['host'];
                }
              else
                {
                 echo $row['show_name'];
                }
echo  " </h1>
        </td>
           </tr>
           <tr>
            <td height='100'>"
             . $row['description_short'] .
           "</td>
       </tr>
       <tr>
        <td align='right'>
             <a href='". $site ."show_page.php?show_id=". $row['show_id'] ."'>More Info</a>
            </td>
           </tr>";
  }

echo "</table>";

}


This function is for a page showing a list of shows from a database. Not all shows have a host. So it does not need to show "with host name" for those shows. I tried if / else statement stating that if there "is" data in the row to display one thing and if there "is not" data in the row to display another.

Here is that piece of code.

Code: [Select]
if ($row['host'] == "")
                {
                 echo $row['show_name']" with " $row['host'];
                }
              else
                {
                 echo $row['show_name'];
                }

I keep getting this error

"Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting ',' or ';' in /home/ansonb/lwr_config.php on line 46"

What am I doing wrong ? I'm sure it is something simple, I just can't figure it out.

I'm just trying something new out here and wanted to know how it looked AND I'm having a hard time figuring out how to accomplish this with the else statement. Obviously on the else it would mean that there was already a template with the same name existing in the database table so I want the user to be sent back to the original form and I'll implement a jquery dialog box telling the user that there is already an existing template with that name.


if (isset($_POST['edittemplate'])) {
    $templatename = mysqli_real_escape_string($dbc, $_POST['templatename']);
    $headercode = mysqli_real_escape_string($dbc, $_POST['headercode']);
    $footercode = mysqli_real_escape_string($dbc, $_POST['footercode']);
    $templateID = (int)$_POST['templateID'];

    $query = "SELECT * FROM `templates` WHERE `templatename` = $templatename";
    $result = mysqli_query ( $dbc, $query ); // Run The Query
    $rows = mysqli_num_rows($result);
    
    if ($rows == 0) {
        $query = "UPDATE `templates` 
            SET `templatename` = '$templatename', `headercode`='".$headercode."', `footercode`='".$footercode."' WHERE `id` = '$templateID'";  
    
    mysqli_query($dbc,$query);
    
    } else {
        
    }
    
    
}

Trying to code a first fit algorithm (explanation here). It doesn't output everything correctly at the end. There probably is an easier way to achieve this, but I need to do it using do and while statements.

From the output I only get the first array, none of the others display.

function first_fit(&$arr, &$max)
{
$bin = array(array(), array(), array(), array(), array(), array(), array(), array(), array() ,array() );
$i=0;
$j=0;

do
{

do

{

if (array_sum($bin[$j])+$arr[$i] <= $max) {$bin[$j][] = $arr[$i]; $k=1;

}

$j++;

}

while($k = 0);

$i++;

$j=0;
}
while($i<=9);
outputarray($bin[0]);
outputarray($bin[1]);
outputarray($bin[2]);
outputarray($bin[3]);
outputarray($bin[4]);
outputarray($bin[5]);
outputarray($bin[6]);
outputarray($bin[7]);
outputarray($bin[8]);
outputarray($bin[9]);
}



The function outputarray() just prints the array in a nicely formatted way.

Any help would be much appreciated.

This page contains a table that is pulling info from a database stored in phpmyadmin. The values entered in that table are passed to the second page:


<?php
include "include/dbc.php";

include "include/header.inc";

$exerciseid = $_POST["exerciseid"];
$duration = $_POST["duration"];
$distance = $_POST["distance"];
$metric = $_POST["metric"];

echo'<h1>Added Activities</h1>';



// name of array
echo '<h1>Exercise</h1>';
if (is_array($exerciseid)) {
        foreach ($exerciseid as $key => $value) {
                        echo $key .' : '. $value .'<br />';
        }
}


echo '<h1>Duration</h1>';
if ($duration == ""){
echo "No value";

}

// name of array
echo '<h1>Distance</h1>';
if (is_array($distance)) {
        foreach ($distance as $key => $value) {

                        echo $key .' : '. $value .'<br />';

        }
}

// name of array
echo '<h1>Metric</h1>';
if (is_array($metric)) {
        foreach ($metric as $key => $value) {

                        echo $key .' : '. $value .'<br />';

        }
}

?>


The problem is that ALL the values, empty or w/content, are being passed. So I was wondering if there was a way to pass only user input with an if/else statement. Something like:


if ($duration == ""){
echo "No value";
else
  echo duration;
}


This, however, is not working and I would like to know what possibly could work that would be structured similarly. Thanks in advance.
