PHP - How To Retain Values In Simple Combo Upon Onchange Event

i am looking for simple php mysql base event calender..that shows upcoming events...i would very helpful for your help.any tutorial.video.or helping link..??

I am attempting to flush values from a URL query with a pagation script.

This line of code will replace one value:
$page_name2 = preg_replace('/&?start=\d+/','',$page_name);

This line of code will replace the second value:
$page_name3 = preg_replace('/&?limit=\d+/','',$page_name);

Can I combine them to replace both values in replace?

This obviously isn't it:
$page_name3 = preg_replace(('/&?limit=\d+/','',)&&('/&?start=\d+/','',)$page_name);

Thank you.

Hi there...

This array thing seems little strange and I had to turn to phpfreaks

I have an array named:
$optionInfo

When we do:

print_r($optionInfo);

it displays all the values stored in the array i.e.

Array ( [4] => Array ( [optionId] => 5 [optionName] => Blue - Medium [optionListId] => 4 [dateCreated] => [enabled] => 1 ) ) 

And as we can clearly see, we have the optionId value as 5. So therefore, when I type:

Code: [Select]
print_r($optionInfo[optionId]);
It returns nothing. Even though there is a value 5 in the array but I just can't get the individual value of optionId.

Is there something I am missing here.

Kindly reply.

Thank you!

Cheers!

 

I'm working on a way to let parents in my son's cub scout pack volunteer for specific spots in a duty roster via an AJAX page and MySQL db.

The duty roster is saved as an array in the db.  My intent is to pull out the array, parse it into XML to send back to the jQuery which asked for it.
The end result right now is that it just displays a bunch of "available" strings in a row, which is the default value for a job slot which hasn't been filled yet. 

The xml should look something like:
Code: [Select]
<data>
<DAY val="DAYVALUE">
<TIMEBLOCK val ="TIMEVALUE">
<JOB title="titlevalue">
<slot num="x">AVAILABLE or NAME</slot>
<slot num="x">AVAILABLE or NAME</slot>
{...}
</JOB>
</timeblock>
</DAY>
<data>
Where the attribute changes to reflect the different days for the campout, and the TIMEBLOCK val attribute changes for the different timeblocks which have job slots (Breakfast, Lunch, etc).

Here is the snippet of code.  The page starts with Header('Content-type: text/xml');  before making the call to the db (I've left that section out for security).  The part where it gets retrieves and traverses the array are working as expected.  It's where the XML gets built that everything goes wonky.  (But if someone can show me a more recursive, efficient way of getting the same effect, I'm all ears)

The output of this page shows up at:http://www.pack238.net/campingregistration/retrievedutyroster.php
You'll see at the bottom where it just says "available available available available available available available available...."
The code is:
Code: [Select]
//start the xml
$xml = new SimpleXMLElement('<data></data>');

//  get the duty roster array from the database
$query = "select dutyroster from ".$eventsTable." where eventID = 1";
$result = mysql_query($query);
if(!$result)
{
}
else{
//put the returned result into a usable array
$returnedRows = mysql_fetch_array($result);
$day = unserialize($returnedRows[0]);
foreach($day as $key => $value) //this gives us each day
{
echo "<Br/> Key is: $key && the value is $value";
$day1 = $xml->addChild('DAY');
$dayValue = $day1->addAttribute('val',$key);
//Here, we know we're at the top level, so parse out the sub arrays
foreach($value as $key1 => $value1)//this gives us each time block
{
$timeblock = "";
$timeblockValue = "";
$timeblock = $day1->addChild('TIMEBLOCK');
$timeblockValue = $timeblock->addAttribute('val',$key1);
echo "<br/>&nbsp;&nbsp;Let's see the time blocks for each day:  $key1   $value1";
//check to see if there's a JOBS sub array yet again or if it's a standalone
if(is_array($value1))
{
foreach($value1 as $key2 => $value2)
{
$job = "";
$title = "";
$job = $timeblock->addChild('JOB');
// $title = $timeblock->addAttribute('title',$key2); //this is the line throwing the attribute error
echo "<br/>&nbsp;&nbsp;&nbsp;&nbsp; We're in a sub array, and the values a   $key2   $value2";
if(is_array($value2))
{
foreach($value2 as $key3 => $value3)
{
//for each slot:
$slot = $job ->addChild('slot',$value3);
$slotnum = $slot ->addAttribute('num',$key3);
echo "<br/> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The jobs a $key3   $value3";
}
}
else //we need to account for individual jobs that don't have a subarray
{
$slot = $job ->addChild('slot',$value3);
$slotnum = $slot -> addAttribute('num','0');
}
}
}
}
// echo "<br/><br/>The array returned is: ".$usableArray."<br/>";
// $usableArray = unserialize($usableArray);
// print_r($usableArray);
}//end of the main foreach
//we got the duty roster array....now just parse out the days, time periods, and jobs then create the xml


$dom = dom_import_simplexml($xml)->ownerDocument;
$dom->formatOutput = true;
echo $dom->saveXML();

echo "<hr/>";
//print_r($xml);

}//end of else to if(!result)

Hi there,

I am working on a PHP web form and I have a very simple situation I guess, I have a variable named: $MyVal

When I do

print_r($MyVal);
To see whats inside, I get:

SimpleXMLElement Object ( [0] => 8.23 )
Now I am assigning this variable into a session variable so that I can do calculations with it.

So I assign:

$_SESSION['MySesVal'] = $MyVal;
But after assigning to session variable, when I do my calculations:

$finalValue = $_SESSION['MySesVal'] * 4;

I get 0. So is it because the actual $MyVal variable has some XML stuff as:

SimpleXMLElement Object ( [0] => 8.23 )

So what is the right way to properly assign $MyVal variable to a session variable to do calculations.

Please reply.

All comments and feedbacks are always welcome.

Thank you!

I am making a project by designing my own MVC model. In this the user accesses controller class which further calls model class which accesses the database by $dbh attiribute defined public. My View is a script which calls different pages. In the constructor of model I'm establishing connection with the database. Firstly I construct the model object when the user accesses i.e. in the controller class to check in the databse then if the username is not present in the dtaabse I want to insert his info in the database for that I again calla model class but this time I again have to establish connection. Is the $dbh firstly constructed is lost like dangling pointers in C++. Do I have to  worry about it. If yes how can I solve this problem.

How do I retain a password as a user navigates from page to page without having to ask him for it again. I do not need it to protect the page, I need it to execute whatever selection he makes.


enter_psw.html  // this is a form
verify_psw.php  // I have the password here
menu1.html  // I don't have the password here and need it
               display_records
               add_record.php
               change_record.php
               delete_record_php

Hi all,

I have a listbox on a form that gets it's data from a MySQL query, all of which is working fine.
I make a selection in my listbox and then submit the form which is reloading itself. However on the reload I would like the listbox to display the selection made by the user, instead it reverts to the first item in the list.
I have included the code, if someone could point me in the right direction that would be great.
I have searched these forums and tried a few things that are suggested but I still can't get it to work.


Code: [Select]
<?php
include("dbconn.php");

$query = "SELECT location.location_name, printer.model_number, location_printer.serial_number" . 
" FROM location, printer, location_printer" .
" WHERE location.location_id = location_printer.location_id" .
" AND printer.printer_id = location_printer.printer_id";
$result = mysql_query($query);

echo "<table>";
echo "<th>Location</th>";
echo "<th>Printer</th>";
echo "<th>Serial No</th>";

while(($row = mysql_fetch_array($result)))
{
    echo "<tr>";
    echo "<td>".$row['location_name']."</td>";
    echo "<td>".$row['model_number']."</td>";
    echo "<td>".$row['serial_number']."</td>";
    echo "</tr>";
}
echo "</table>";

if(isset($_POST['location']))
{
$loc = $_POST['location'];
echo "<p>Location = <b> $loc </b>";
} 

?>

<html>
<head>
<title>Loop Results</title>
</head>
<body>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" >
<table>
        <tr>
        <td>
            <?php
     $query = "SELECT * FROM location ORDER BY location_name";
$result = mysql_query($query);

$default = $_POST['location'];

echo "<p>Location: ";
echo "<select name='location'>";
while(($row = mysql_fetch_array($result)))
{
echo "<option value='{$row['location_id']}";

//Selected value
if($row['location_id'] == $default)
echo " selected ";

echo "'>{$row['location_name']}</option>\n";
}
echo "</select>";
?>               
            </td>

I have a listener which executes a HTTP request to a remote API before the User entity is persisted and uses the response to set one of the entity's properties.  It will also listen for update and remove and will make the appropriate HTTP request to the API but will not modify the entity.  All works as desired... Almost.  If when persisting the entity, I have some error, the remote API and my application become out of sync.  I wish to change my application to perform a second call to the API if an error occurs and reverse the previous call.  My thoughts on how to implement a

Place a try/catch block when executing the query.  Don't like this approach. Add an ExceptionListener which somehow retrieves the entity and makes the applicable changes.  Maybe part of the solution, but too complicated to be the full solution. When adding, updating, or deleting a user from the remote API under UserListener's three methods, adding a callback which gets executed upon a PDOException.  I think this is the best approach and expanded my thoughts below.

 

<?php

namespace App\EventListener;

use Doctrine\Persistence\Event\LifecycleEventArgs;
use App\Service\HelpDeskClient;
use App\Entity\AbstractUser;

final class UserListner
{
    private $helpDeskClient;

    public function __construct(HelpDeskClient $helpDeskClient)
    {
        $this->helpDeskClient = $helpDeskClient;
    }

    public function prePersist(AbstractUser $user, LifecycleEventArgs $event)
    {
        $this->helpDeskClient->addUser($user);   //$user will be updated with the HTTP response
    }

    public function preUpdate(AbstractUser $user, LifecycleEventArgs $event)
    {
        $this->helpDeskClient->updateUser($user);
    }

    public function preRemove (AbstractUser $user, LifecycleEventArgs $event)
    {
        $this->helpDeskClient->deleteUser($user);
    }
}

Okay, how do I actually do this?  Was thinking of modifying UserListner as follows:

//...
use Symfony\Component\HttpKernel\KernelEvents;

final class UserListner
{
    // ...
    
    public function prePersist(AbstractUser $user, LifecycleEventArgs $event)
    {
        $this->helpDeskClient->addUser($user);
        
        $event->getObjectManager()->getEventManager()->addEventListener(KernelEvents::EXCEPTION, function($something) use($user) {
            // Use $this->helpDeskClient to reverse the changes
        });
    }
    
    // Similar for update and remove
}

 

But when trying this approach, I get a PDOException, but my callback never gets excecated.  I've also tried replacing KernelEvents::EXCEPTION with '\PDOException' (note the quotes) with no success.

Any ideas what I should be doing differently?

Maybe some totally different approach?  I suppose I could make the request to the API after the DB query is complete for updating and deleting, but not for adding.

Hi all,   I am trying to validate all required fields in my contact form using php.


However I am unable to retain what was selected in my country dropdown list after it is selected and

submitted if the form had errror while validating.

I want the form to retain the value that was selected by the user to stay in the form so that users can

make necessary changes and resubmit the form   all other values stay in the form except the country dropdown.   Please help

Hi,

I have set up 2 php pages

page 1 - add_entry2.php
In this page I have a invoice table created where I can dynamically add/delete rows. This has a View Bill button which takes me to page 2- add_entry3.php
In this page it shows up the rows added in page 1 in read only format, so if the user wants to modify the data that he/she entered then he must Click on <back> that i have provided in the page 2 which will direct him to page 1

Now the problem starts here
on click of Back the dynamically added rows dissappear..which is frustrating..I know its something to do with my code..but can anyone help me fix it.

One more thing is that i dont want to store the data into DB till the finalise button is clicked on page 2 so that means till page 2 is submitted nothing goes to DB from Page 1. 

here is the code(I have removed the java script functionalities to reduce length of the post)

add_entry2.php

Hello JS experts,   I'm new to JS coding (self-learning) and I have just one (potenitally) simple request to ask of you wonderful folks here.   Oh BTW, I've tried searching through this forum (and the WWW as well) but couldn't seem to easily find something that fits my request, or was easy for me to understand and apply to my situation.   So what I have/want is: a Data-Entry form which (for the first record/entry for a given date) allows the user to select a date from a "Calendar Date Picker".  Upon subsequent records/entries (for the same date), the date field should no longer be accessible, but the (previously entered/selected) value should be both displayed (greyed-out) and certainly carried over to the DB/Table.   I know this might be a very simple piece of code, but being that I'm a newbie, I'm not sure how to achieve this.   Would appreciate any and all help to get this done (preferably the necessary code).   If it helps, here's some of my existing code that's related to the field names:   Form field details:

                <div class="control-group">

                    <label class='control-label'>Select Flyer Start Date:</label>

                    <input type="text" name="datepicker" id="datepicker">

                </div>

DB (table) field details:

         $flyerDateStart = isset($_POST["datepicker"]) ? $_POST["datepicker"] : "";

Thanks much.

I was wondering how to write something like this:

if (table1.column1 + table2.column2 > table3.column3  then .....

I am confused where to put ( ) and '
