PHP - Calling Function By Click And Result Throwing Error

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.

When I click on the letter of the alphabet on my form page, it will bring up the results of my query.  I got this part working.  The next part is to be able to click on any of the populated results and have it autofill my form with organization, first name, last name, email address and phone number.   I know that I need to use Ajax and jQuery to accomplish this.    Here is my html

<!-- Letter Search -->
<div class="searchBox span12">

Here is my php

if(preg_match("/^[A-Z | a-z]+/", $_POST['name'])){

}

if(isset($_GET['by'])){
$letter=$_GET['by'];

//query to sort by last name

$sql="SELECT contact_id, first_name, last_name, church_org, email_address, phone_number FROM ics_data WHERE last_name LIKE '$letter%' ORDER BY last_name ASC";

//run the query against the mysql query function
$result=mysql_query($sql); 

//count results
$numrows=mysql_num_rows($result);

echo "<p>" .$numrows . " results found for " . $letter . "</p>"; 

//Create while loop and loop through result set
while($row=mysql_fetch_array($result)){

echo "</ul>";
echo "</div>";
}
}

Here is my Javascript file (Ajax)

$(document).ready( function() {
	function formfill() {
		var organization = $('#organization').val();
		var firstname = $('#firstname').val();
		var lastname = $('#lastname').val();
		var email = $('#email').val();
		var phone = $('#phone').val();
		$.ajax ({
			method: "GET",
			url: "search.php",
			dataType: 'json',
			data: {
				organization:organization, firstname:firstname, lastname:lastname, email:email, phone:phone
			},
			type: "POST",
			success: function(data) {
				$organization
				$firstname
				$lastname
				$email
				$phone
			},
			
	 	failu  function() {
                alert('fail!');
            }
        });
	}
  

I know that I do not have a reference yet to JSON in my php file and that it is needed.  I'm not solid on the Ajax part.  That is the part that is tripping me up.  I know that I need to make the form autofill when clicking on a specific result returned from my query... but i'm not sure how to do that.   Thank you in advance for any help or advice you can give!!   I am relatively new to programming.  Hopefully I posted this in the right forum as a lot of these technologies overlap.

Hi, I got a little problem with calling a PHP function from a href.
I got my site all set up, and am calling the function like this:

Code: [Select]
<?php echo '<a href="'.changeRecentPosts().'" class="image">' ?>
This does indeed work, but it calls the function every time I refresh my page.. Which isn't the effect I was trying to achieve.

I tried to change it to : Code: [Select]
<?php echo '<a href="#" onClick="'.changeRecentPosts().'" class="image">' ?> But that didn't work either.

It also seems it only calls it when I refresh my page, but never when I click it (I guess because PHP is handeled before HTML or something similar?).

If you can think of any way (even in AJAX, or whatever other language...) feel free to, I think I can figure it all out.

Thank you! 

I am using simple machines forum, and by placing a link to ssi.php in the top of my php page Code: [Select]
<?php require_once('/forum/SSI.php');?>I am able to use some ssi functions. My problem is calling another function from within a function. My first function is this:
Code: [Select]
<?php

$allowed_groups = array(1,5);
$can_see = FALSE;
foreach ($allowed_groups as $allowed)
if (in_array($allowed, $user_info['groups']))
{
$can_see = TRUE;
break;
}

if ($can_see)
{
echo '
<div>
this is text that i want certain groups to see
</div>';
}
else
{
//message or section to show if they are not allowed.
echo 'this is text that i dont want certain groups to see';



}
?>
This is my second function:
Code: [Select]
<?php ssi_welcome(); ?>
I want to put the second function inside the first function, like so:
Code: [Select]
if ($can_see)
{
echo '
<div>
<?php ssi_welcome(); ?>
</div>';
this just gives me the "<?php ssi_welcome(); ?>" displayed on the actual site, it is not calling the separate function.

I have tried different approaches, e.g. $function ssi_welcome;  but all it does is display this as text as well..

Please can some one point me in the right direction. Thank you

Hi guys,

           I am having a tough time executing the code inside the javascript. Everything is working fine with the Php code and I am able to see the output of variable myValue too.. But the problem is nothing is being executed inside the javascript..Not even the first statement of the javascript..When I look at the output sent by the HTML to the browser, the output is what is listed after this code which is right at the bottom of this page. Please advise.

HEllo I wanted to know wheter php function can be call in js functions. Please Help.

can someone help me I am trying to call a class function using a varible.... example
say i go to index.php?page=contact i want to pull that class with out doing a switch statement can someone help me
Code: [Select]
<?php
$Site = page;
$Site->getPage($_GET['page']);
?>
Code: [Select]
<?php
class page extends site {

function getPage($page) {
return $this->$page;
}
function Contact() {
echo '<h2>Contact test</h2>';
echo '<form>

</form>';
}

}
?>

Whenever I want to use AJAX (using jQuery) I store the PHP code in a seperate file and then send an retrieve data from that file using AJAX.  However I was wondering if you can just call a PHP function.  Then it would save me having to put each function in a seperate file?

Thanks for any help. 

Hi all!

First off, sorry if this question is a completely dumb one but i'm really new to PHP.

I'll paste the code to start with...


function getReasons ($id)
{
   global $link;
   $rst = mysql_query('SELECT r.name as reason FROM entries_feedback_comments as f LEFT JOIN reasons as r ON r.id = f.reason_id WHERE f.feedback_id ='. $id, $link);
   while ($row = mysql_fetch_assoc($rst))
   {
      echo $row['reason'];
   }
}


later on in the code.... inside a table structure i do this...

   echo '<tr class="' . ($y?'even':'odd') . '">';
   echo '<td colspan="10" class="freetext">'.getReasons($row['id']).'</td>';
   echo '</tr>';
   echo '<tr class="' . ($y?'even':'odd') . '">';
   echo '<td colspan="10" class="freetext">'.$row["freetype"].'</td>';
   echo '</tr>';


(I have left put the "freetype" bit of code in to show you that it works with this row but not with the function).

Basically, what I see is the result of the function outside of the table itself rather than in the table row.
Is there a reason for this? Does a function have to be put in specific places in the code?

Thank you for your help.

Hi,

I was looking around the web for a image resizer script and I came across this one.
http://www.scriptol.com/scripts/thumbnail-maker.php

The weird thing is, it says to use this syntax to get it to work
php resizer.php -j myimage.png 

Well.. I don't seem to understand how that makes it work, Normally I would run a php script by looking for it's main function and running it like:

mainfunction();

Maybe I'm interpreting it wrong,  but how is this script suppose to run?

I have this piece of code:
Code: [Select]
function newmessage() {
  box = new LightFace({
title: 'New message',
width: 600,
height: 400,
  content: "<form method='post' action='sendmessage.php'>To: <br><input type='text' name='to'><br><br>Subject: <input type='text' size='94' name='subject'><br><br><textarea name='message' rows='13' cols='63'></textarea><br><br><input type='submit' value='Send' name='send'><input name='from' type='hidden' value='<? echo $username; ?>'></form>",
buttons: [
{
title: 'Close',
event: function() { this.close(); }
}
]
});
box.open();
}
As well as this piece of code:
Code: [Select]
$userid = mysql_real_escape_string($_SESSION['userid']);
    //WALLNOT
   $db2 = "SELECT status FROM comments WHERE touser='$username' AND status='0'";
   $db2connect = $database->query($db2);
   
   $status2 = "SELECT status FROM friends2 WHERE user2='$username' and status='0'";
   $test = $database->query($status2);
   
   $statfromdb = "SELECT stat FROM wallposts WHERE person='$username' AND stat='0'";
   $status = $database->query($statfromdb);
   
   $GetStatus = "SELECT byuser, status, dtime FROM commentstatus WHERE status='$Naw'and person='$username' AND byuser!='$username'";
   $ConnectGetStatus = $database->query($GetStatus);
   
   $Getmsg = "SELECT status FROM messages WHERE status='0' AND touser='$username'";
   $ConnectGetmsg = $database->query($Getmsg);

   $row = mysql_fetch_array($test);
   $row2 = mysql_fetch_array($ConnectGetmsg);
   $getrow = mysql_fetch_array($status);
   $getrow2 = mysql_fetch_array($db2connect);
   $StatusComment = mysql_fetch_array($ConnectGetStatus);
   
      //Select profile picture
$GetProfilePicture = "SELECT profilepicture FROM users WHERE username='$username'";
$ConnectProfilePicture = $database->query($GetProfilePicture);
$ProfilePicture = mysql_fetch_array($ConnectProfilePicture);
$MyProfilePicture = $ProfilePicture['profilepicture'];
That I use in 19 different pages, is there anyway I can put them all into one page, and just them through a function?

It takes so much time when loading if I have it on each page?

And if you have any other tips how to optimize my loading speed please write them.

Thank you in advance!

*Edit: Bad grammar.

When ever I try to google this I always get it the other way round "Calling PHP from jQuery" which is now what I need.

Basically I want, When the script starts, For PHP to check if an array is empty and if it's not call a jQuery function (This would be the jQuery UI Dialog box).

If you can help me here or even post a link to a resource then I will kiss ya. No homo.

Thanks in advance!

Trying to run this function so it displays the generated image in a table cell -

Code: [Select]
<?php 
function imgsecuregen($size = 6){ 

$width = 11*$size; 
$height = 25; 

$string = ""; 
for($i = 1; $i <= $size; $i++){ 
$string .= rand (0,9).""; 
} // for 

$im = ImageCreate($width, $height); 
$bg = imagecolorallocate($im, 102, 102, 102);  // background
$black = imagecolorallocate($im, 0, 255, 0);   // text
$grey = imagecolorallocate($im, 102, 102, 102);    // border 
imagerectangle($im,0, 0, $width-1, $height-1, $grey); 
imagestring($im, 5, $size, 5, $string, $black); 
imagepng($im); 
imagedestroy($im); 
} 

imgsecuregen(8);  // string length

?>

Works if I load it directly, but not in a <td>.
 

Thanks in advance for help.
I have a PHP script that has a function called traverseXMLNodes and it passes an xml string. I want anyone with a username and password to be able to call this function from his website or application or programming. In short i want my site to act as an API(Application Programming Interface).

 I am really stuck as to how to go about this. There are other functions i would like to call as well so traverseXMLNodes  is not the only function i want to my "API" users to access.

Below is the code I am using. the filename for my php i called remote.php. I am using the following query string to test and no results are returned.
http://localhost/testfolder/remote.php?xmlstring=20


Code: [Select]
<?php
$allowedfuncs = array('xmlstring','remotefunction2');
 
if(in_array($_get['xmlstring'], $allowedfuncs))
{
    $func = $_get['xmlstring'];
    $output = traverseXMLNodes($func);        // This calls $_get['funccall']()
    echo $output;
}
else
{
    exit();
}
 
 function traverseXMLNodes ($func) {
 
 echo "The XML string is";
 echo "<br/>";
 echo $func;
 echo "<br/>";
 }
/*
More functions go here
*/
?>
