Can someone explain this code to me?

/*CALL Controllers CLASS IF EXIST*/

			if($row){ 

				$this->load->ClassValidation = false;

				$this->className = str_replace("-",'_',$row->slug);

				$this->load->controller( $this->className );

				if(method_exists( $this->load->{$this->className}, index ))

					$this->load->{$this->className}->index($data);

				else

					$this->load->view( $row->folder.'/'.$row->goto, $data ); //default

			}

			else

				$this->load->view( $row->goto ); //!$row- page not found

Thank you.

I am trying to to provide basic information on an organization like : "Currently there are (variable) number of members".  I have no problems building tables or getting the queries to work in mysql.  I just can't transfer the variables into the php output.

The php artisan command was working fine.  

I just tried to create a new migration file and it failed with:

 [ErrorException]
  Invalid argument supplied for foreach()

Even if I run "php artisan list" it fails with the same error.  I don't know what I did.  How can I track down what is causing the issue?

Hi,

I've been using the below code for sometime, all works well, except when there is an insert or edit query - I get a blank page.
It could be because it's trying to add/edit a field that may not exist in the database or an SQL error - but I do not get feedback on screen - the page usually just loads blank.  Should I be using different code, alter it, or something completely different?

$db_host = "ip";
$db_user = "admin";
$db_name = "database";
$db_pass = "pass";

$link = mysqli_connect($db_host, $db_user, $db_pass) or die(mysql_error());
mysqli_select_db($link,$db_name) or die(mysql_error());

Select all Open in new window

QUERY

$sql = mysqli_query($link,"SELECT * FROM table") or die(mysql_error());
$row = mysqli_fetch_array($sql);
$total = mysqli_num_rows($sql);

Select all Open in new window

INSERT

mysqli_query($link,"INSERT INTO table (test) VALUES ('1')");

Select all Open in new window

UPDATE

$result = mysqli_query($link,"UPDATE table SET test='1',WHERE id = '1'") or die(mysql_error());

Select all Open in new window

Or is it a PHP setting i need to turn on to properly show me the SQL error?

Thank you

By default you can get the list of post titles followed by the date of the post. As shown below. However as in the second list I would like a list but with breaks in the list to show when the month has changed. How is this possible.

Post 1 title
Post 1 date
Post 2 title
Post 2 date
Post 3 title
Post 3 date
Post 4 title
Post 4 date
Post 5 title
Post 5 date
Post 6 title
Post 6 date

What I want is :

July 2017
-
Post 1 title
Post 1 date
Post 2 title
Post 2 date
Post 3 title
Post 3 date

June 2017
-
Post 4 title
Post 4 date
Post 5 title
Post 5 date
Post 6 title

This function along with the PHP is sending the email.  What it is not doing is hiding the form and saying "Thanks"...so it is only half working!

The Function

<script>
$(function() {
  $("#myform").on('submit', function(e) {
    e.preventDefault();
    $.ajax({
      url: 'send_mail.php',
      dataType: 'json',
      data: $("#myform").serialize()
    }).done(function(d) {
      if (d.success==true) {
        $("#myform").hide();
        $("#results").text("Thanks!").show();
      }
    });
  });
});
</script>>

I have a text box on a php page residing on my apache web server which has the following:
"£300 plus other text lines"

The page is uft-8 encoded
The text "£300" is displayed correctly on my web server - ie the "£" sign comes across correctly
If I send the details of this text box via a php form, the "£300" comes out as "£300"

Can someone explain what is happening and how I can get rid of the £ and replace with £

Hello

I'm busy on a project where i have read only access to an oracle database.
Got a running webserver (LAMP) with a running OCI8 connection.
I'm trying to get a select query result from the following:

TableA
ID
DOC_ID
Date
Type

TableB
ID
DOC_ID (references tableA)
FILE_NAME
FILE_ID
FILE_TYPE

TableB can contain more then one result for the same DOC_ID.

The goal is to get the data from TableA appended with the results from TableB where the DOC_ID is the same and get them into a JSON format.
Looking like

{
	"data": [{
		"ID": "123456",
		"DOC_ID": "789456",
		"Date": "2/1/2016",
		"Type": "PI",
		"FILE_NAME": [
			"File1.pdf", "File2.docx"
		],
		"FILE_TYPE": [
			"PDF", "DOCX"
		],
		"FILE_ID": [
			"453215", "654687"
		]
	}, {
		"ID": "544569",
		"DOC_ID": "001223",
		"Date": "2/8/2016",
		"Type": "PI",
		"FILE_NAME": [
			"File1.txt"
		],
		"FILE_TYPE": [
			"TXT"
		],
		"FILE_ID": [
			"453215"
		]
	}, {
		"ID": "2225599",
		"DOC_ID": "0148966",
		"Date": "2/1/2017",
		"Type": "PI",
		"FILE_NAME": [
			"File1.xml", "File2.xml", "File3.xml"
		],
		"FILE_TYPE": [
			"XML", "XML", "XML"
		],
		"FILE_ID": [
			"00147788", "00114455", "00113210"
		]
	}]
}

Hi experts, i want to change PHP to POWERBUILDER, any help please!
below the php script :

I am using this code.  Whenever an email is sent another page pops up (thank_you.html) saying thank you.  I don't want that.  I simply want the input field that previously said "Your Email Here" to now say.  "Thank You".    How can I do this?

www.mediascrubber.com/videos.html

Its at the very bottom of the page.  Subscribe.

I assume I would do an echo "Thank You" of some sort.  But where?

<form class="form-horizontal" action="send_mail.php" method="post">
				<div class="input-group">
                <input type="text" name="email_address" class="def-input" placeholder="Your Email Here">
                <span class="input-group-btn">
                <button class="btn-form btn" input type="submit">Subscribe</button>
                </span>
                <!--input type="submit" value="Submit" /-->
				</div>
                </form>
