PHP - Seeking Multiple Methods Or Options

My website is http://www.infotechnologist.biz.   We handle Web Site Development, web app development, and mobile development. No project is too big, or too small.   Contact me today with details.   My number is 4049390637.

It appears that I have PHP 5.1.6 on my VPS and it is unstable when using filter_var($_POST['email'], FILTER_VALIDATE_EMAIL).

Can someone recommend a reasonable Regular Expression to replace this faulty function?

(Not looking for overly complicated, just something that will block out outrageous e-mails.)

Thanks,


Debbie

Hello:

I would like to know how I can add the option to upload JPGs and/or PDFs to the form I have.

I believe I will need to allow 3 uploads once the whole form is done, but I'm trying to keep it small as I learn this.

Currently, the form saves the data to the database, and emails the results to a contact. This is fine - just what I need to do most of the time.

However, what I'm interesting in doing for this form is to allow the end user to upload/attached JPGs and/or PDFs and save then to the database (and I believe I will need to save the files in a folder on the server, I have one called "EmailedImages"),
and then email the results to the contact, including links that will allow the contact to click and download the attached JPGs and/or PDFs.

I haven't done this before, so can someone point me in the direction of how to do this, or should an example with the code I use:
Code: [Select]
<?php

$error = NULL;
$myDate = NULL;
$FullName = NULL;
$Email = NULL;

if(isset($_POST['submit'])) {

 $myDate = $_POST['myDate'];
 $FullName = $_POST['FullName'];
 $Email = $_POST['Email'];

 
 if(empty($FullName)) {
   $error .= '-- Enter your Full Name. <br />';
 }
 
 if(empty($Email)) {
   $error .= '-- Enter your Email. <br />';
 }

if($error == NULL) {

$sql = sprintf("INSERT INTO myContactData(myDate,FullName,Email) VALUES ('%s','%s','%s')",

                        mysql_real_escape_string($myDate),
                        mysql_real_escape_string($FullName),
                        mysql_real_escape_string($Email);

                        
  if(mysql_query($sql)) {
  
    $error .= 'Thank you for contacting us.';
    
mail( "email@mywebsite.com", "Contact Request",

"Date Sent: $myDate\n Full Name: $FullName\n Email: $Email\n",
"From: $Email" );
  }
  else {
    $error .= 'There was an error in our Database, please Try again!';
  }
}
}
echo '<span class="textError">' . $error . '</span>';

?>



<form name="myform" action="" method="post">
<input type="hidden" name="myDate" size="45" maxlength="50" value="<?php echo date("F j, Y"); ?>" />


Full Name: <input type="text" name="FullName" size="45" maxlength="50" value="<?php echo $FullName; ?>" />
Email: <input type="text" name="Email" size="45" maxlength="50" value="<?php echo $Email; ?>" />


<input type="submit" name="submit" value="Submit" />

</form>

Any help would be greatly appreciated!

In <div id="chart_rt">%3$s</div> below, it is populated with a string that always begins with a number followed by a colon (from 1: to 25:). I see that ltrim removes characters from the beginning of a string but I don't see how to compensate for the extra character in 10: through 25:


function wp_rss( $url, $num_items = -1 ) {
    if ( $rss = fetch_rss( $url ) ) {
        echo '<div id="charts">';

        if ( $num_items !== -1 ) {
            $rss->items = array_slice( $rss->items, 0, $num_items );
        }
//start count
$i = 1;
        foreach ( (array) $rss->items as $item ) {
            printf(
                '<div id="chart_lt">'.$i.'</div><div id="chart_rt">%3$s</div>',
                esc_url( $item['link'] ),
                esc_attr( strip_tags( $item['description'] ) ),
                htmlentities( $item['title'] )
            );
//increment
$i++;
        }

        echo '</div>';
    } else {
        _e( 'An error has occurred, which probably means the feed is down. Try again later.' );
    }
}

This has probably been asked a bunch of times , but :

I only recently started to self learn PHP , and this small project i am making is quite a challange for me.
The scripts below are not realy writen by me , but i wished to tie them together to get a fully working code.

What is suppose to happen is :

In the form i wish to put a special button that puts extra input fields in the form.

After the form is submited ,with whatever amount of feilds in it, the data goes to a processing.php file that sorts all the info gathered and finaly sends all this data formated in to the last file that will be inluded in the index.php.

i already have the code for increcing the amount of inputs but the problem is , all inputs have the same names. Coz of that i get a mess.

What i need is each input to have a unique name or id , that way the processing file would receive different names(id's) with different values(what ever is writen in the inputs by users).

for example:

I have 2 enitial fields displayed on  form.html , i click the button "add new" 5 times and add 5 more input fields.
All this data must be sent to a process.php and on the output write all of this information formated in the last file in a row that will be displayed in the index by useing
<?include("blablabla.php");?>

The input increment is done by a java script. the problem is sending data with unique id(name) and receiving it.

The form file :

<?include("header.php");?>





 <?$i = 1; ?>

   <script type="text/javascript">

   function validate(frm)
   {
        var ele = frm.elements['feedurl[]'];

       if (! ele.length)
        {
            alert(ele.value);
        }

       for(var i=0; i<ele.length; i++)
       {
          alert(ele[i].value);
       }

      return true;
 }

  function add_feed()
 {
      var div1 = document.createElement('div');

     // Get template data
     div1.innerHTML = document.getElementById('newlinktpl').innerHTML;

     // append to our form, so that template data
     //become part of form
     document.getElementById('newlink').appendChild(div1);

 }


   var ct = 1;

   function new_link()
   {
   ct++;
  var div1 = document.createElement('div');
  div1.id = ct;

  // link to delete extended form elements
 var delLink = '<div style="text-align:right;margin-right:65px"><a href="javascript:delIt('+ ct +')">Del</a></div>';

 div1.innerHTML = document.getElementById('newlinktpl').innerHTML + delLink;

document.getElementById('newlink').appendChild(div1);

}
 // function to delete the newly added set of elements
 function delIt(eleId)

in the code above i tryed to make the programm POST the numbers in the name increcing it by 1. But when i click submit i get offset error.

The processing file :

$i =1;
####################################################################################

if(($_POST['prodname']!="")&&($_POST['price']!="")){

    ############################################################
    $writetocsv = $_POST['prodname1'] . "," . $_POST['price1']"%" <BR> . $_POST[$i] . $_POST[$i];
             $fp = fopen("data/data.csv", "a");
             fwrite ($fp,$writetocsv);
             fclose ($fp);
                            echo "<script>alert('Data sent.')</script>";
}
else{
    echo "<script>alert('Error! Please fill the form!')</script>";
}
echo "<script>location.replace('index.php')</script>";
?>

Perhaps someone knows a easyer way , since i am not sure how to make stuff due to the lack of knowlage in php. I also tryed arrays but , as said before , too tough when you are a noob

Please help.

what are magic methods? when do we need to use magic methods? what are the advantages of using magic methods? thanks in advanced.

hey guys im wdondering if there's a magic method which works like  

__GET()

    but allows you to put a parameter in...thank you

<?php

class test
{
      public function run()
      {
              $this->object->('string');
              // __get with parameter?
       }

       public function __get($value)
       {
              return $this->{$value}
       }
}

?>

I don't know if this belongs here; sorry if it doesn't.

I'm using a method=get on a form as I need to pass information through a URL once the form has been submitted.
But I also need to INSERT some data from that form to multiple tables.

- How can I stop the GET from passing my other variables into the URL?
- How do I make the form submit to itself? I need to use the 'index.php?p=checkout' as this matches with a switch statement, which matches to the checkout page. The function PHP_SELF will just refresh to the index.php page, which will not have any of this checkout's page validation.

Here's my code:
Code: [Select]
<h2>Please enter your details</h2>
<h3>All fields required</h3>
<div id="checkout">

<?php

if (isset($_GET['checkout'])){
require_once ('./includes/connectvars.php');

$title = $_GET['title'];
$fname = $_GET['fname'];
$sname = $_GET['sname'];
$ctype = $_GET['ctype'];
$cnumber = md5($_GET['cnumber']);
$syear = $_GET['smonth'] . $_GET['syear'];
$fyear = $_GET['fmonth'] . $_GET['fyear'];
$service = $_GET['cardAuth'];
$amount = $_REQUEST[$total];
$msg = rand(1000,9999);
$api = 'd41d8cd98f00b204e9800998ecf8427e';
$b_house = $_GET['b_house'];
$b_postcode = $_GET['b_postcode'];
$b_city = $_GET['b_city'];
$b_country = $_GET['b_country'];
$d_house = $_GET['d_house'];
$d_postcode = $_GET['d_postcode'];
$d_city = $_GET['d_city'];
$d_country = $_GET['d_country'];

$dbc = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);

$query = "INSERT INTO customer
 (cust_id, first_name, last_name) VALUES ('', '$fname', '$sname')
  ";
$query = "INSERT INTO bill 
  (cust_id) VALUES ('')
  ";
$query = "INSERT INTO deliver
  (cust_id) VALUES ('')
  ";
  
 mysqli_query($dbc, $query);
}

hello,

i have been following the php.net oop manual but im having a little trouble understanding something.

on this page in the manual: http://uk3.php.net/manual/en/language.oop5.basic.php
it shows this code and if i seperate it out i cant get it to echo the results i want. what am i doing wrong?
i have added a little extra code .

class Bear
Code: [Select]
class Bear {
    // define properties
    public $name;
    public $weight;
    public $age;
    public $sex;
    public $colour;

    // constructor
    public function __construct() {
       
                $this->name = "winny the poo";
$this->weight = 100;
$this->age = 0;
$this->sex = "male";
$this->colour = "brown";
    }

    // define methods

    public function eat($units) {
        echo $this->name." is eating ".$units." units of food... <br/>";
        $this->weight += $units;
    }

    public function run() {
        echo $this->name." is running... <br/>";
    }

    public function kill() {
        echo $this->name." is killing prey... <br/>";
    }

    public function sleep() {
        echo $this->name." is sleeping... <br/>";
    }


}

class PolarBear
Code: [Select]
class PolarBear extends Bear {

    // constructor
    public function __construct() {
        parent::__construct();
        $this->colour = "white";
        $this->weight = 600;
    }

function polarbar()
    {
        // Note: the next line will issue a warning if E_STRICT is enabled.
        Bear::bear();
    }

    // define methods
    public function swim() {
        echo $this->name." is swimming... ";
    }
}


now if i try to get back the results i have trouble.

this is fine
Code: [Select]
$bear = new Bear();

$bear->eat($units);
$bear->eat();
$bear->run();
$bear->kill();
$bear->sleep();

that echos back
Quote

//THE BEAR
winny the poo is eating 5 units of food...
winny the poo is eating units of food...
winny the poo is running...
winny the poo is killing prey...
winny the poo is sleeping...

//THE POLAR BEAR
winny the poo is eating 5 units of food...
winny the poo is eating units of food...
winny the poo is running...
winny the poo is killing prey...
winny the poo is sleeping...
winny the poo is swimming...



THAT FINE but how come i can echo out each of the properties?
why do these ways not work?

Code: [Select]
Bear::eat($units);
Bear::eat();
Bear::run();
Bear::kill();
Bear::sleep();

or

Code: [Select]
$bear = new Bear();
$bear->$name;
$bear->$weight;
$bear->$age;
$bear->$sex;
$bear->$colour;

or

Code: [Select]
echo Bear::eat($units);
echo Bear::eat();
echo Bear::run();
echo Bear::kill();
echo Bear::sleep();

or

Code: [Select]
$bear = new Bear();
echo $bear->$name;
echo $bear->$weight;
echo $bear->$age;
echo $bear->$sex;
echo $bear->$colour;

and the same goes for PolarBear

if i try and get back any of the properties on a page i get nothing ???

i even tried putting it in a loop and that didnt work
Code: [Select]
$bear = new Bear();

foreach ($bear as $bears){
echo $bears->$name;
echo $bears->$weight;
echo $bears->$age;
echo $bears->$sex;
echo $bears->$colour;
}

whats wrong.
why cant i get any results from these ?
thanks

Hi, I am trying to get my head around classes, interfaces and methods for different animals

 

this is what I have so far:

<?php 
interface animal {
  function walk();
  function fly();
  function swim();
}
class monkey implements animal{
  const interface1 = "I am from test class";

  function noise() {
    echo "ooh ooh ah ah!";
  } 

  function walk() { 
    echo "monkey is walking";
  }
  function fly() { 
    echo "monkey is Flying";
  }
  function swim() { 
    echo "monkey is Swimming";
  }
  public function display() {
    echo monkey::interface1;
    echo PHP_EOL;
  }

}

class bear implements animal{
  const interface1 = "I am from test class";

  function noise() {
    echo "Grrr!";
  } 

  function walk() { 
    echo "Bear is walking";
  }
  function fly() { 
    echo "Bear is Flying";
  }
  function swim() { 
    echo "Bear is Swimming";
  }
  public function display() {
    echo bear::interface1;
    echo PHP_EOL;
  }

}
$Obj = new monkey();
$Obj->display();
$Obj1 = new bear();
$Obj1->display();
?>

I'm a bit stumped as  animal interface not calling all functions?! please help

Hi, I'm new to php and am attempting to build a site where the navigation and content is built with query functions. 
My current tables in my database are Categories, Products, and Variation.  So a person chooses a category -> then a product -> then a product page shows variations for that product. The problem I am currently having is after when a person selects a section the previous section selected is reset.  So lets a person selects a category the product list is shown, but when a person selects a product, the category is no longer selected in the navigation.  Or if someone selects product and sees all the variations, if he selects a variation the product ID is reset.  I've tried to comb through the internet for some type of solution.  I came across concatenating URL encode, but am not sure if this is the correct solution.  I tried concatenating one of my urls
with Code: [Select]
"<a href=\"product_detail.php?cat=" . urlencode($sel_cat["id"]) . '&' . "product=" . urlencode($sel_product['id']) . '&' . "var=" . urlencode($var["id"]) . "\"
its a bit of a stab in the dark. 

My $_GET function is
Code: [Select]
function find_selected_product() {
global $sel_cat;
global $sel_product;
global $sel_var;
if (isset($_GET['cat'])) {
$sel_cat = get_cat_by_id($_GET['cat']);
} elseif (isset($_GET['product'])) {
$sel_cat = NULL;
$sel_product = get_product_by_id($_GET['product']);
} elseif (isset($_GET['product'])) {
$sel_product = get_product_by_id($_GET['product']);
$sel_var = get_default_var($sel_product['id']);
} elseif (isset($_GET['var'])) {
$sel_product = NULL; //test
$sel_var = get_variation_by_id($_GET['var']);
} else {
$sel_cat = NULL;
$sel_product = NULL;
$sel_var = NULL;

}
}
My navigation code is
Code: [Select]
function public_navigation($sel_cat, $public = true) {
$output = "<td class=\"c1\"><div class=\"sidenav\"><ul>";
$cat_set = get_all_cats($public);
while ($cat = mysql_fetch_array($cat_set)) {
$output .= "<li>";
if ($cat["id"] == $sel_cat['id']) { $output .= "<a class=\"current\""; }
$output .= "<a href=\"index.php?cat=" . urlencode($cat["id"]) . "\">{$cat["cat_name"]}</a></li>";

}
$output .= "</ul>";

return $output;
}
My product is divided into gender and is written like

Code: [Select]
function cat_content_ladies($sel_cat, $sel_product, $female = true)
{
$output = "<ul class=\"regions\">";
$cat_set = get_all_cats($female);
while ($cat = mysql_fetch_array($cat_set))
{ if ($cat["id"] == $sel_cat['id'])
{
$product_set = get_products_for_female($cat["id"], $female);
$output .= "<tr>";
while ($product = mysql_fetch_array($product_set))
{
if ($cat["id"] == $sel_cat['id'])
{
$output .= "<tr>";

My variation table is set up in thumb nails and is written in this function
Code: [Select]
function show_thumb($sel_product, $sel_var, $public = true)
{
$output = "<ul class=\"subjects\">";
$product_set = get_all_products($public);
while ($product = mysql_fetch_array($product_set)) {
$output .= "<li";
if ($product["id"] == $sel_product['id']) { $output .= " class=\"selected\""; }
//$output .= "><a href=\"product_detail.php?product=" . urlencode($product["id"]) .
//"\">{$product["id"]}</a></li>";
if ($product["id"] == $sel_product['id']) {
$var_set = get_variations_for_product($product["id"], $public);
$output .= "<ul class=\"pages\">";
while ($var = mysql_fetch_array($var_set)) {
$output .= "<li";
if ($var["id"] == $sel_var['id']) { $output .= " class=\"selected\""; }
$output .= "><a href=\"product_detail.php?var=" . urlencode($var["id"]) .
"\">{$var["id"]}</a></li>";

}
$output .= "</ul>";
}
}
$output .= "</ul>";
return $output;
}

 


any light on this subject would be greatly appreciated.

I am trying to run the function "age", using the last line, I thought that is how I could to access that method, but that doesn't work.
Code: [Select]
<?php
require_once '../phpLive/phpLive.php';
$live->myClass = (object)array(
"name" => "Billy Bob Joe",
"age" => function($dob){
// Run some code
}
);
echo $live->myClass->age("1986-07-22");
?>
I get the following error when trying to do that.
Quote

Fatal error: Call to undefined method stdClass::age() in /xxx/new.plugin.php on line 9


Any Ideas how I can access that method?

Thanks!

Is there any way to produce a custom magic method?

Let's say when I try to get an attribute that doesn't have any value, a method gets called that gives that attribute a value.

So I want a method to be triggered when I try to get a value from an attribute that doesn't have any value.

I just have a quick question, what happens if I don't assign a visibility element to methods?

In other words, if I just have:

[php]
class Article_model
{
   public $data;

   function index()
   {
      return $data;
   }
[php]
...instead of declaring public, private, static, and so on before the function. Will php just consider it public?
