PHP - Submit Refresh Problem

Hello,

I am trying to load an external image from a NOAA site directory. This image refreshes every three hours, starting with 0 and then 3,6,9,12.....21 in a 24 hour calendar, and are stored for days in advance. The date/time is in the file name. Originally I had written the script to refresh on the hour, and then realized the tri-hourly spacing. This is what I have:

Code: [Select]
<?php
date_default_timezone_set('Etc/GMT-1');
$today = date("YmdH");
$pattern = '/WaveHeight_'.$today.'_mic.png';
$base_url = 'http://www.crh.noaa.gov/images/greatlakes/ndfd/MIC/dynamic2';
print '<a href="http://www.crh.noaa.gov/greatlakes/?c=map&l=lm&p=a"><img src="'.$base_url.$pattern.'" width= "237" hieght= "314" " ></a>';
?>

I am not fluent in php, but I assume I need a "If H=1,4,7,10,13,16,19,22; Then H+2 ; along with If H=2,5,8,11,14,17,20,23; Then H+1" to keep the images relatively current. I just can't quite wrap my head around how to express this.

Any help is appreciated.

Thank you.

Hi!!!
i created this code for my chatroom!!
Code: [Select]
<?php $usern=$_SESSION['etchat_'.$this->_prefix.'username'];
$con1 = mysql_connect("localhost","manosir_main","***********");
if (!$con1)
  {
  die('Could not connect: ' . mysql_error());
  }
mysql_select_db("manosir_manoshos_main", $con1);
$query = "SELECT etchat_user_online_user_sex AS gender
          FROM db1_etchat_useronline
          WHERE etchat_user_online_user_name = '$usern'";
$result= mysql_query($query);
$user = mysql_fetch_assoc($result);



if($user['gender']=='m'){ ?> <span style=" font-size: 12px; font-family: tahoma; direction: rtl; font-weight: bold; color: #0000FF " > male</span>
 <?php } if($user['gender']=='f'){ ?>  <span style= "font-size: 12px; font-family: tahoma; direction: rtl; font-weight: bold; color: #FF47D1" > female</span><?php }  
mysql_close($con1); ?> it gets the users`s username when he login from session and get his/her sex by mysql!!!!!  the starnge part is this:  when i login to page it doesnt work..but when i refresh the page it works       in first opening the $usern is empty!! 
whats wrong!!!!!!!

Hi all,

Thanks for reading.

I'm running a script using jQuery that auto-refreshes a <div> on the index page from an external PHP script to get all the rows in a database and display them on the index page. The script works great - here it is as follows:

Code: [Select]
<script type="text/javascript">

$(document).ready(function() {

$("#responsecontainer").fadeOut("fast").load("getrows.php").fadeIn("slow");

var refreshId = setInterval(function() {
$("#responsecontainer").fadeOut("fast").load('getrows.php').fadeIn("slow");
}, 5000);

$.ajaxSetup({ cache: false });

});

</script>

The getrows.php script I'm working with looks like this:

Code: [Select]
<?php 

$rowsQuery = mysql_query("SELECT * FROM Happenings WHERE HappeningDate='$today'");

if (mysql_num_rows($rowsQuery) == 0) {
$happeningsToday = "There are no happenings today.";
} else {

$allHappeningsToday = 1;

while ($getHappeningsToday = mysql_fetch_array($rowsQuery)) {

$happeningName = stripslashes($getHappeningsToday['HappeningName']);
$happeningDate = $getHappeningsToday['HappeningDate'];
$happeningDescription = $getHappeningsToday['HappeningDescription'];

if ($allHappeningsToday == 1) {

$happeningsToday .= "
<div class=\"box\">
<p>".$happeningName." | ".$happeningDate." | ".$happeningDescription."
</div>";

$allHappeningsToday = 2; 

} else { 

$happeningsToday .= "
<div class=\"box\">
<p>".$happeningName." | ".$happeningDate." | ".$happeningDescription."
</div>";

$allHappeningsToday = 1; 

}

}

}

echo $happeningsToday;

?>

This script works great as well.

Currently, the auto-refresh jQuery script as you can see if getting and fading in/out all of the rows.

Off of the above getrows.php script, is there a way after I could get only the newly created rows since the last refresh and only fade those in and out while leaving the others already loaded by the auto-refresh script to not fade in/out?

Any ideas, thoughts or suggestions would be unbelievably helpful.

Thank you very much.

when i upload a link using the form below it adds \ into it like this <a href=\"http://www.google.co.uk\" target=\"_blank\">test</a> and the link is unusable with them any way to stop this

<?php
include("dbinfo.inc.php");
mysql_connect($localhost,$username,$password);
@mysql_select_db($database) or die( "Unable to select database");
$query="SELECT * FROM News WHERE id='$id'";
$result=mysql_query($query);
$num=mysql_numrows($result); 
mysql_close();

$i=0;
while ($i < $num) {
$News=mysql_result($result,$i,"News");
 

?>
<form action="updated.php">
<input type="hidden" name="ud_id" value="<? echo "$id"; ?>">
News:<br> <TEXTAREA NAME="ud_News" COLS=40 ROWS=6><? echo "$News"?></TEXTAREA><br>
<input type="Submit" value="Update">
</form>

<?php
++$i;
} 
?>

Hello everyone, this is my first post here! My question covers a PHP, SQL, and HTML so I apologise if this isn't the appropriate section to post this message.

Outline to my problem: A user can search my database for a variety of events, which are then listed on a results form. Next to each result I have an option to add this event to the users personal area as a 'saved event' for future reference. Currently I have a solution whereby an HTML form sends an action to '#', inserts the event ID and member ID into the 'savedevent' table via a PHP/SQL function. The page then displays 'event added'. THIS WORKS.

However, if the user navigates away from the page, and then back to it again, the PHP script is obviously run again, ie- a 'resend data' dialog box is displayed to the user, which I really don't want.

This website:http://www.bandsintown.com/event/3988178-nme-awards-tour-2011-london-united-kingdom-live-at-o2-academy-brixton-on-february-19-2011 achieves exactly what I am trying to do with the 'attending' button, but I cannot figure out how they accomplish this.

Any help and ideas would be greatly appreciated.

Hello again, and thanks!
paddyfields.

Hi im a newbie php developer and am experiencing two problems at the moment. The first and most important is that google charts can not save over https i have copied a function that should save the file but i am clueless as to how it work s and where i am going wrong with it ??? any help with this would be greatly appreciated. Secondly every time i hit submit the page first posts data and then i have to submit again before it posts the data to google charts api ?

Again any help would be greatly appreciated Thanks in advance ill add all the code here for you guys.

Saving the google chart api

function saveImage($chart_url,$path,$file_name)
{
   if ( (!file_exists($path.$filename)) || (md5_file($path.$filename) != md5_file($chart_url)) )
   {
      file_put_contents($path.$filename,file_get_contents($chat_url));

   }
   return($filename);
}

function doSomething()
{
   $local_image_path ="home/sean/img/charts/";
   $imagename="some_chart_image.png";
   $chart_url = $chartimage;
   $image = saveImage($chart_url ,$local_image_path,$image_name);
   echo "Image Saved";
}

$body .=   "<table class='formTABLE'>
      <tr>
      
      <TD class='FieldCaptionTD' align='right' colspan='2'>
         <input class='Button'  method='post' action='' align='right' type='submit' name='save_file' value='Save'>
         <input class='Button'  method='post' action='' align='right' type='submit' name='submit_button' value='Submit'>
         </center>            
      </TD>
   </tr>
   </table>";
$body .= htmlmaintsplit();
?>
<img src="/home/sean/work/some_chart_image.png" alt="" />

How am i to use this now to save the graph i have created ???

Relating to the submit button problem - this is set after the submit button though i have tried placing the submit button beneath this code but still the same problem persists

<form action='<?php echo $action?>' method='POST' name='bargraph' value='bargraph' chid='post_form'
onsubmit="this.action = 'http://chart.apis.google.com/chart?chid=' + (new Date()).getMilliseconds(); return true;">

Say I have an "Entries" table. I want to submit same multiple entries using a form submission. And If I have other queries submitted in the same form, I want those quarries to be submitted only once.  Is that possible to do? 

Here's my code.

if(isset($_POST['submit'])) {

  $entries = 10;

  $id   = 55;
  $name = 'Smith';

  $insert = $db->prepare("INSERT INTO entries(id, name) VALUES(:id, :name)");
  $insert->bindParam(':id', $id);
  $insert->bindParam(':name', $name);
  $result_insert = $insert->execute();
  if($result_insert == false) {
    echo 'Fail';
  } else {
    echo 'Success';
  }

}
?>
<form action="" method="post">
  <input type="submit" name="submit" value="SUBMIT" />
</form>

Hi.  Pretty straight forward I guess but as the name suggests am a newbie.  I have a form that requires the user to enter certain parameters.  If the values are blank it submits to itself and loads the error messages.  What I want to do is create PHP code that submits the form to a different url.  What I thought was create two forms (the second with hidden fields replicating the first form), each form having a different url in the action"" code.  What I cant work out is the PHP IF ELSE code to submit form 2 if Form1 is is validated correctly.  This is the PHP code relevant to the form validation.  Help?

<?php
      //If form was submitted
      if ($_POST['submitted']==1) {
          $errormsg = ""; //Initialize errors
          if ($_POST[width]){
             $title = $_POST[width]; //If title was entered
          }
          else{
             $errormsg = "Please enter width";
          }
          if ($_POST[drop]){
             $textentry = $_POST[drop]; //If comment was entered
          }
          else{
             if ($errormsg){ //If there is already an error, add next error
                $errormsg = $errormsg . " & content";
             }else{
                $errormsg = "Please enter drop";
             }
          }
      }

      if ($errormsg){ //If any errors display them
          echo "<div class=\"box red\">$errormsg</div>";
      }

      //If all fields present
      if ($title && $textentry){
         //Do something
          
echo 'THIS IS WHERE I WANT THE CODE TO SUBMIT FORM 2 or SUBMIT FORM 1 TO A DIFFERENT URL';
      }   
      ?>

the info posts beautifully i just canst seem to get the button to auto click or submit, tried numerous ways!  help

So basically, My Bulletfactory page is playing up. Every 30 minutes the bulletfactory should produce bullets, it is producing the bullets fine, but only when someone views the page (after 30 minutes is up). If there any kind of PHP refresh for this? Or do i just use normal refresh?

Thanks

will refresh a page every second will cause some crash or error ??
cause when i try this, it sometimes display this error

"Warning: mysql_connect() [function.mysql-connect]: Can't connect to MySQL "
this is occur when i run it in my local server. I am so worried if this might also happen when i run it online.

thanks

I've been doing some searching, but I can't figure this out, as I don't know enough about JS.   I have found a tutorial that does this

But I don't know what exactly I can remove, what needs to stay (as far as the js), and where exactly I insert my ad code that is in a <script> tag of its own... but that also has a <noscript> tag as a fallback. While I understand I need to change the refresh from 3 secs, can someone help me take out the example JS code, and tell me where I would put my JS ad code? And do I simply remove the <script tags from my ad code, when inserting it into an area that is already between <script> tags?   Any help on this would be appreciated, thanks!

Hi all,

I am having some trouble with a part of code. Basically the code is set for a Factory to produce 750 items every 30 minutes. It does this fine IF AND ONLY IF someone clicks the Factory page. For example, it produces 750 bullets, then I leave the page alone for say 20 minutes, but when I click back, it doesn't have 10 minutes left before the next produce. Instead, It has 30 minutes. So it only produces when someone on the game clicks the page. I have tried the basic html refresh but that doesn't work.

Any idea's?

Thanks in advance

hello,
