That website uses javascript for pagination, splitting data across 3 pages. They also have a function to list all their data on one page but it requires clicking the link on the page which runs a javascript AJAX call. I want to pull all that data with PHP but how do I emulate the Javascript AJAX call in my code so I can get all that data instead of just the first page? Even if I could just call that function and then parse the information it returns to me. Thanks.
How can i call javascript function from php code??

Some help will be very welcome. It seesm that the new table class is not working in this function if I pass the values to it, I have tested the class, it does get the post values I post to it so $_POST['id'] are being received as well as all the other $_POST's but the table class and find function is not working, it works fine if I don't put it in a function.. function edit() { if (isset($error)){ $error.="Please fix the error(s) above";} else { if ($_POST['id'] <> "") { $update =& new table($db, 'publisher'); $update->find($_POST['id']); $update->name = $_POST['name']; $update->url = $_POST['url']; $update->contact = $_POST['contact']; $update->address = $_POST['address']; $update->phone = $_POST['phone']; $update->email = $_POST['email']; $update->save(); $error = "The Publisher has been edited"; } } } This topic has been moved to Other Libraries and Frameworks. http://www.phpfreaks.com/forums/index.php?topic=319682.0 I can call the following function successfully as a single php program // Acknowledge and clear the orders function ack($client, $merchant, $id) { $docs = array('string' => $id); $params = array('merchant' => $merchant, 'documentIdentifierArray' => $docs); $result = $client->call('postDocumentDownloadAck', $params); return $result; } with $result = ack($t, $merchant,'2779540483'); successful output [documentDownloadAckProcessingStatus] => _SUCCESSFUL_ [documentID] => 2779540483 I'm trying to figure out how to call this function as an object from another program. Trying the following gives error ***Call to a member function call() on a non-object*** function postDocumentDownloadAck($t, $merchant, $id) { $this->error = null; $docs = array('string' => $this->id); $params = array('merchant' => $this->merchant, 'documentIdentifierArray' => $docs); ** I've tried the following which does nothing $result = $this->soap->call('postDocumentDownloadAck', $params); ** I've tried the following - which gives error "Call to a member function call() on a non-object" $result = $this->t->soap->call('postDocumentDownloadAck', $params); if($this->soap->fault) { $this->error = $result; return false; } return $result; } *** calling program snippet for above function $merchant= array( "merchant"=> $merchantid, "merchantName" => $merchantname, "email"=> $login, "password"=> $password); $t = new AmazonMerchantAPI($merchantid, $merchantname, $login, $password); $documentlist= $t->GetAllPendingDocumentInfo('_GET_ORDERS_DATA_'); $docid = $documentlist['MerchantDocumentInfo'][$i]['documentID']; $docs = array('string' => $docid); $ackorders = $t->postDocumentDownloadAck($t, $merchant,$docs); Any ideas of what I'm doing wrong are greatly appreciated. Is this even possible? I'm trying to call function nameGen from in the function nameGen but I just get an error saying cannot redeclare. I only want it to return $newName when it is not in the array $takenVals. can this only be done with another loop and a constant somewhere? Code: [Select] $newVarVals = array(); $takenVals = array(); $varCount = count($varArray); // contents are set else where and is fine for($i = 0 ; $i < $varCount; ++ $i) { function nameGen(&$varCount,&$takenVals){ $newName = rand(0,$varCount); if(in_array($newName,$takenVals)) { nameGen(&$varCount,&$takenVals); } else{ return $newName; } } $newName = nameGen(&$varCount,&$takenVals); $takenVals[] = $newName; $newNameToKeep = '$_'.$newName; $newVarVals[] = array('oldName' => $varArray[$i], 'newName' => $newNameToKeep); } error: Cannot redeclare nameGen() okay in modlogs.php i have a function Code: [Select] <?php function modmenu($page) { ?> <dl><dt class="<?php if ($page == 'modlogs') echo '';else echo 'ust'; ?> LEFT" style='margin-left:5px'><a href='mlogs.php'><b>User Logs</b></a> </dt><dt class="<?php if ($page == 'modlogs1') echo '';else echo 'ust'; ?> LEFT"><a href="modlogs1.php">Topic/Forum Actions</a></dt> <dd> <?php } ?> in modlogs1.php i try to echo Code: [Select] modmenu('modlogs1'); to show the menu but i get unidentified function? lol isn't functions global wtf?

Edited by alphasil, 04 December 2014 - 10:32 AM. I'm writing a program that allows users to input a stock and view a historical price chart. Code is straight out of libchart charting library. Problem is, user is supposed to enter the stock symbol from a form handler (index.php) which then passes the symbol as a variable to the charting function, which doesn't get called at all:
<? php
function index() { chart($_POST['userinput']};
} ?> .
<?php
function chart($stock)
{
$prices=getdata($stock); //returns array of prices from yahoo finance
$data=analyzer($prices); //produces metrics to be charted
graph($data); } ?> //plots the metrics, outputs .html
chart.php works on its own, as I've verified by hardcoding $argv='ibm'; in its code body. But index.php can't seem to call chart.php, as I've verified by including an echo/var_dump line in chart.php (doesn't get executed at all). It doesn't have anything to do with form handling either, as chart('ibm'); doesn't call chart.php either. I don't understand how a 6-line piece of code can be so problematic. All files are in the same folder, btw.
Thanks.
Code: [Select] <html> <center> <form method="post" action=""> <b>Email</b><br><input type="text" name="email"/><br> <b>Password</b><br><input type="password" name="password"/><br> <input type="submit" name="submit" value="Login"/><br> </form> <?php if(isset($_POST['submit'])){ echo echo_post($_POST['email']); function echo_post($postvar){ return $postvar; } } ?> </center> </html> the filename is index.php How come I get the undefined function echo_post on line 14? I know it is probably something simple but I am kind of new to this, if you could help me out that would be great I'd like to set my own error handler function to clear some session variables, but I do not want to completely replace php's internal error handler message reporting. Is there any way to mimic the internal error message reporting so I can define my own error handler function. function myErrorHandler(){ unset($_SESSION['var']); // HERE EXECUTE Normal PHP error message reporting } Thanks I've made this code for a very simple registration form practice:
//assign form variables
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$username = $_POST['username'];
function clean_names($dirty_name) {
strip_tags($dirty_name);
str_replace(' ', '', $dirty_name);
ucfirst(strtolower($dirty_name));
//return $dirty_name;
}
$names = array($firstname, $lastname, $username);
if(isset($_POST['register_button'])) {
// WHY IS THIS FUNC CALL NOT WORKING??
foreach($names as $name) {
clean_names($name);
}
echo "First Name: " . $firstname . "<br>";
echo "Last Name: " . $lastname . "<br>";
echo "Username: " . $username . "<br>";
}
The values are returned but they haven't been put through the clean_names function. I am getting this error: Parse error: syntax error, unexpected '[', expecting ')' in C:\xampp\htdocs\Work\Store\store.php on line 154 when I run the following code: Code: [Select] function categorySearch($sql) { $res = mysqli_query($this->conn,$sql); $this->results='<table>'; while($cRow = mysqli_fetch_array($res)) { function getCategoryName($cRow[0]) $this->results .= '<tr><td style="border: thin solid #000000;">' . $this->cat_str . '</td></tr>'; } $this->results.='</table>'; return $this->results; } Line 154 refers to this line: function getCategoryName($cRow[0]) Can anyone see what the problem is? This is the error that I am getting...

I am attempting to dynamically generate values for Wordpress shortcodes ( [example] ). I have successfully created the shortcodes and am having trouble setting their value. When I call the function that is supposed to return the value for the shortcode, it returns empty. I can however hard code a string and have it returned to the function, thereby manually creating a value for the shortcode. However, because the shortcodes are being generated and filled dynamically, I need this function to work without specific values. I know this may sound like a Wordpress specific question, but I have a feeling it's just my lack of understanding of PHP operations. So, here is the basic layout: The name of the shortcode is generated from within a foreach loop that retrieves the name of custom fields on the post ($keyName). Code: [Select] $custom_field_keys = get_post_custom_keys(); foreach ( $custom_field_keys as $key => $keyName ) { $valuet = trim($keyName); if ( '_' == $valuet{0} ) continue; if ( get_post_meta($thePostID, $keyName, true) ) : $fieldName = get_post_meta($thePostID, $keyName, true); endif; $fieldValue = $_GET["$keyName"]; add_shortcode((string)$keyName, 'myFields'); } The add_shortcode function has two parameters ('name_of_shortcode', 'function_name'): Code: [Select] add_shortcode((string)$keyName, 'myFields'); I need the myFields function to return the value of $fieldValue from within the foreach loop. That's where the problem lies. This doesn't work: Code: [Select] function myFields() { $myString = preg_replace('/[^a-zA-Z\s]/', '', $fieldValue); return $myString; } This does work: Code: [Select] function myFields() { return 'Content to replace the shortcode'; } This code will replace [shortcode] with "Content to replace the shortcode" in the post. The ultimate goal is: when [$keyName] appears anywhere within the post, it will display the content returned by the myFields function ($fieldValue). However, it's not working. I can't seem to pass the value of $fieldValue to the myFields function and thereby return it to add_shortcode. Any help is appreciated and I am awaiting anxiously to answer any questions. Here's all the code together: Code: [Select] function myFields() { $myString = preg_replace('/[^a-zA-Z\s]/', '', $fieldValue); return $myString; } $custom_field_keys = get_post_custom_keys(); foreach ( $custom_field_keys as $key => $keyName ) { $valuet = trim($keyName); if ( '_' == $valuet{0} ) continue; if ( get_post_meta($thePostID, $keyName, true) ) : $fieldName = get_post_meta($thePostID, $keyName, true); endif; $fieldValue = $_GET["$keyName"]; add_shortcode((string)$keyName, 'yourFunction'); } what's wrong in this line $tpl->set('main_content',set_block($heading,'center',$err_tpl->fetch(load_template('error.tpl')))); |
