PHP - If Statement In The Middle Of String Concatenation?

I have a regex that validates a string. I want to ensure there is no space in the string. Thus far I have used the negative look ahead regex construct as shown below to match strings without spaces.

(?!.*(\s))

While this prevents space in between a word, all strings with space characters at the end or beginning are getting validated. I do not want that at all.   This is the full regex script below:

$string = "#JebiamgoOeing0";
if (preg_match('/^.*(?=.{8,})(?!.*([A-Za-z0-9])\1{1})(?=.*[a-z])(?=.*[A-Z])(?!.*(\s))(?=.*[\d])(?=.*[\W]).*$/', $string))
{
    "do something";
}
else
{
   "do something else";
}

I need help in resolving this.   Thank you.

I need an if statement, but i have no idea how or if it can be done.

If a text string is greater than 10 characters, {echo $string}   else{  print $error }
<?php

$string = '1900800008';
$error = 'String isn't long enough';
if(  ?????????  ){echo $string}
else{  print $error }

?>

Hello again.

I run a sports league website and registrations received after a certain date need to have their league fees calculated to add 10%.  someone wrote this for me a couple of years ago, but I have since then lost the full code.  Need to know how to add a date to the follow statement that would automatically add the 10%. 

Can someone look at this for me and fill me in on what's missing?
Thanks!
Code: [Select]
    /*
     * Calculate fees
     */
    $intSize = intval($arrLeagueSearch['size']);
    switch($intSize)
    {
        case 2:
            $dblBase = 150.00;
            $intBSize = 3;
            break;
        case 4:
            $dblBase = 330.00;
            $intBSize = 6;
            break;
        case 6:
            $dblBase = 550.00;
            $intBSize = 10;
            break;                       
        default: die("Invalid league size");
    };
 
    $dblEarlyTeam = $dblBase;
    $dblEach = $dblEarlyTeam / $intPlayers;
/*
    $dblLateTeam = $dblEarlyTeam * 1.10;
    $dblLateEach = $dblLateTeam / $intPlayers;
*/

Hi,
My issue here is that I cant get my query string variables to ONLY feed into if/else statement  on my secondary page. I include my secondary page (fine.php) from my index page. My query string variables keep being fed back into my original if/ese statement on index.php.

here is the if/else on index.php (these links work fine):

<?php
if($_SERVER['QUERY_STRING']=='/index.php' || $_SERVER['QUERY_STRING']=='')
{
include 'port.php';
}

elseif (isset($_GET['pos'])){
include 'pos.php';
}

elseif (isset($_GET['web'])){
include 'web.php';
}

elseif (isset($_GET['fine'])){
include 'fine.php';
}

        else {include '404.php';}






here is the if/else on my secondary page (fine.php). These links are supposed to alert the if/else in the next table cell. However, they instead alert the if/else in index.php.


<td><br/>
<a href="?backset"><img src="fine/thumbs/x-backset.jpg" border="0"></a><br/><br/> 
<a href="?backside"><img src="fine/thumbs/x-backside.jpg" border="0"></a><br/><br/> 
<a href="?bannerprint"><img src="fine/thumbs/x-bannerprint.jpg" border="0"></a><br/><br/> 
<a href="?chopu"><img src="fine/thumbs/x-chopu.jpg" border="0"></a><br/><br/> 
</td>
<td><br/>
<div id="DivPiece" align="left">
<?PHP 

if (isset($_GET['backset'])){
       include 'fine/backset.php';
}

elseif (isset($_GET['backside'])){
     include 'fine/backside.php';
}

elseif (isset($_GET['bannerprint'])){
     include 'fine/bannerprint.php';
}

elseif (isset($_GET['chopu'])){
include 'fine/chopu.php';
}

?>
</div>
</td>



How can I get the links on the secondary page to only alert the if/else statement on that page, and BLOCK the if/else statement on index.php from seeing them? I still want to use the query string though.

Thanks!

Hi All,

I'm working on PHP scripts to interact with a web hosted MySQL DB for an Android Application.

Simply what I am trying to do is in the PHP script is run a SELECT statement which will return the value of a column, UserType, and compare the result of this to a string, which will then execute code depending on it's value. This user type can only be either 'student' or 'lecturer'. Any help with this would be much appreciated. 

<?php

    require "init.php";
	
	$user = $_GET["userID"];
	
	#Selects column account type where the idNum equals $user which is passed from my app.
	$sql1 = "select accountType from user_info where idNum = '$user'";
	$result1 = mysqli_query($con,$sql1);
	$row1 = mysqli_fetch_assoc($result1);
	
	#This is where I am stuck. Simply, I am trying to run the code in the loop where the result of $sql1 equals 'Student'. The else will run if it is not 		#student and therefore is 'Lecturer'. I'm also not sure if my code inside the IF is fully correct either as it's not running that far.

	if($row1['accountType'] == 'Student')
	{
		$sql2 = "select courseCode from user_info where idNum = '$user'";
		$result2 = mysqli_query($con,$sql2);
		$row2 = mysqli_fetch_assoc($result2);
		
		$sql3 = "select * from module_details where classListCourseCode = '".$row2['courseCode']."'";
		$result3 = mysqli_query($con,$sql3);
		$response = array();
		
		while($row = mysqli_fetch_array($result3))
		{
			array_push($response,array("moduleID"=>$row[0],"lecturerID"=>$row[1],"moduleName"=>$row[2],"classListCourseCode"=>$row[3]));
		}
		
		echo json_encode(array("server_response"=>$response));
	}

Thanks in advance.

How do I add a space in my concatenation?  What I have down below doesn't work.


$result[0] .$result[1]

I have a table (applicants) which has a number of fields including 5 for potential 'parties' - these are party1, party2, party3, party4 and party5. Any particular applicant will always have two parties but could have any number up to 5.

I need to export a pdf (which I can do) but I need it to include data drawn from the applicants table in the format:

party1, party2 and party3 OR party1 and party2 etc

that is, each party has a comma after it except the last but one, which has no comma but an 'and'. (I hope this is clear enough!)

I can't work out how to do this for a varying number of 'parties'.

Any suggestions/answers gratefully received.

I am currently learning Zend/PHP on the fly. I've gone from 0 to 40 in about 2 months, as far as savviness is concerned. I am working on a form that I want to display array information of two things (shortname and fullname) in a drop-down list. I am thinking I need to do some sort of concatenation to achieve this, or would I do an array within an array? The array is defined in a value object and that draws the id, shortname and fullname. Shortname is the defined label in that file. In the form page, i have the LO ['full_name'] => LO ['label']... this inputs the right information into the database, but shows the full name. I want the drop-down to show it as following: Shortname|Fullname. This will be used in a couple of places once I get on the right track on how to accomplish this. I would be accepting of any help, as well as any resourced that could answer my question and help me finish this form.
 

Cheers,
ESK

problem is when i select unpaid in drop down box
it not show the expected result.

Is there a subtle difference between
$array[] = 'item';
vs
$array[] .= 'item';

Thank you.

I can successfully concatenate strings and vars to assemble a php var using an echo statement like this:

Code: [Select]
echo "<input type='radio' id='radio_btn_" . $Row['question_number'] . "_0' name='question[question_" . $Row['question_number'] . "]' value='0' checked='checked' />";
However, when attempting to reference the same var in an IF statement, I can't seem to get the syntax right. I know this syntax is wrong, but I list it for reference to describe the issue I am trying to solve.

Code: [Select]
if ($_POST['radio_btn_' . $Row['question_number'] . '_0'] == '0'){
I also tried curly braces but can't arrive at a solution. Any advise would be appreciated.

I'm wondering if this is at all possible:-

Code: [Select]

$i = 7;

$row_item['comment$i_name'] = "john";


with the $i in $row_item['item$i_id'] being replaced with whatever $i is set as sort of like this:-

$row_item['comment.'$i'._name']

Is this sort of concatenation possible inside array element names as I can't seem to get it to work?

Hi guys; 

I've managed to find my way into something of a maze. 

<td> <a href="'Details/21/index.php'"?id= . $id .'>" . $row['id'] . "</a> </td> 

I'm looking at this line in the code. I realise it's currently in the wrong syntax but I'm just trying multiple different variations.

At the moment I'm actually just trying to make it go to a static link but my real goal is to - get it to pick up the id number, of the id row I click, and concatenate that with the rest of my address string. Then use that as the href. 

Something like this: -

"'Details/' + $id + '/index.php'"

It's really confusing me though inside this loop and for some reason the id number is being picked up as an int, by the looks of things. It's getting above my level of understanding. 

Any chance one of you masters would through a n00b a lifeline? 

 

This is my code below 

 

<!DOCTYPE html>
<html>
<head>
	<title>LifeSaver DB</title>
	<h1> LifeSaver Database </h1>
</head>
<body>
	<table>
		<tr>
			<th>Id</th>
			<th>Location</th>					
			<th>Initials</th>
			<th>TimeStamp</th>
			<th>Notes</th>					
		</tr>
		<?php
		$conn = mysqli_connect("localhost", "meh", "pas", "DB"); 
		// Check connection
		if ($conn->connect_error) {
			die("Connection failed: " . $conn->connect_error);
			}
			
		$sql = "SELECT * FROM LifeSaver1 ORDER BY id DESC";
		$result = $conn->query($sql);
		
		if ($result->num_rows > 0) {
			// output data of each row
			while($row = $result->fetch_assoc()) {
				
				//for href row
				$id = $row['id'];
				$Footage = ['Footage'];
				
				echo 
				"<tr>
					<td> <a href="'Details/21/index.php'"?id= . $id .'>" . $row['id'] . "</a> </td>                
					<td>" . $row["Location"] . "</td>		
					<td>" . $row["Initials"]. "</td>
					<td>" . $row["TimeStamp"]. "</td>	
					<td>" . $row["Notes"] . "</td>
							
				</tr>";}
				
				//show table
				echo "</table>";
				} else { echo "0 results"; }
			$conn->close();

	?>

I can log-in, and get to the page with the two links on it. However, once I click one of the links it falls back to the log-in page, and it ends up being a never ending loop.

It's doing this:
Log-In --> Page with links ---> Log-In page again

Should be doing this:
Log-In --> Page with links --> Add Product page or View Products page

I can never get into the the actual sub page.

Just to be clear, the address bar actually shows product=add or product=view, but it still shows the log-in page.
