PHP - Just Want To Add A Space At The Beginning Of Return
The below code returns a radio list after an input box in a profile edit section.
All I want to do is add a space at the beginning of the radio list so to separate the input box and the radio list. Where the magic happens here is on this line: return $selhtml . ' ' . getFieldIcons( $_CB_framework->getUi(), $required, null, $fieldHandler->getFieldDescription( $field, $user, $output, $reason ), $fieldHandler->getFieldTitle( $field, $user, $output, $reason ) ); I've tried several variations of trying to use &nspb; both in the return string directly as well as creating a var for it. I've tried various ways of wrapping it in a div to simply add a margin, I've tried kicking my dog, I've tried banging my head against the wall, nothing seems to work. I either get a t var error, an unexpected something or other like . or & error depending on what I'm doing, or it tries to divide by zero using /'s. Here's a larger view of the code: function onFieldIcons( &$fieldHandler, &$field, &$user, $output, $reason, $tag, $type, $value, $additional, $allValues, $displayFieldIcons, $required ) { global $_CB_framework, $ueConfig, $_CB_fieldIconDisplayed; if ( is_object( $field->params ) ) { $privacyLevel = $field->params->get( 'plug_cbprivacy_level' ); } else { $privacyLevel = 0; } if ( $displayFieldIcons && ( $reason != 'search' ) ) { if ( ( $privacyLevel == 1 ) && ( $field->profile != 0 ) ) { $privacy =& moscomprofilerPrivacy::getInstance( $user, 'field', $field->fieldid ); $selected = ( $privacy ? $privacy->rule : '' ); $selectorName = $field->name . '___cbprivacy'; $connTypes = array(); if ( $this->params->get( 'conns_by_type', 0 ) ) { if ( $ueConfig['connection_categories'] ) { $connTypes = explode( "\n", $ueConfig['connection_categories'] ); foreach ( array_keys( $connTypes ) as $k) { $connTypes[$k] = trim( $connTypes[$k] ); } } if ( $selected == 2 ) { $type = $privacy->getParam( 'conn_cat' ); if ( $type ) { $selected = $selected . '|*|' . $type; } } } $options = array(); $options[] = moscomprofilerHTML::makeOption( '', '' . CBTxt::T(' ') ); if ( ( $ueConfig['allow_profileviewbyGID'] == -2 ) && $this->params->get( 'prop_registered', 1 ) ) { $options[] = moscomprofilerHTML::makeOption( '1', '' . CBTxt::T(' ' ) ); } if ( $ueConfig['allowConnections'] ) { $prop_connections = $this->params->get( 'prop_connections', 1 ); if ( $prop_connections ) { $options[] = moscomprofilerHTML::makeOption( '2', '' . CBTxt::T( ' ' ) ); } if ( count( $connTypes ) > 1 ) { foreach ($connTypes as $type ) { $options[] = moscomprofilerHTML::makeOption( '2|*|' . htmlspecialchars( $type ), ( $prop_connections ? ' ⌊ ' : '' ) . '' . sprintf( CBTxt::T( 'Only for %s' ), $type ) ); } } if ( $this->params->get( 'prop_fofs', 1 ) ) { $options[] = moscomprofilerHTML::makeOption( '3', '' . CBTxt::T( 'Also for friends of friends' ) ); } } if ( $this->params->get( 'prop_invisible', 1 ) ) { $options[] = moscomprofilerHTML::makeOption( '99', '' . CBTxt::T( ' ' ) ); } $selHtml = moscomprofilerHTML::radioList( $options, $selectorName, '', 'value', 'text', $selected, 2, false ); if ( isset( $_CB_fieldIconDisplayed[$field->fieldid] ) ) { return $selHtml; } else { $_CB_fieldIconDisplayed[$field->fieldid] = true; return $selHtml . ' ' . getFieldIcons( $_CB_framework->getUi(), $required, null, $fieldHandler->getFieldDescription( $field, $user, $output, $reason ), $fieldHandler->getFieldTitle( $field, $user, $output, $reason ) ); } } else { if ( isset( $_CB_fieldIconDisplayed[$field->fieldid] ) ) { return null; } else { $_CB_fieldIconDisplayed[$field->fieldid] = true; return getFieldIcons( $_CB_framework->getUi(), $required, $field->profile, $fieldHandler->getFieldDescription( $field, $user, $output, $reason ), $fieldHandler->getFieldTitle( $field, $user, $output, $reason ) ); } } } else { return null; } } The basic layout here is this: |inputbox||radio list| But I want: |inputbox| |radio list| Similar TutorialsI 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.
Edited by terungwa, 25 October 2014 - 12:50 PM. I'm reading through this book which is actually not bad but, on page 286 there's a shopping_cart.php code (which I downloaded from the web site). The code that seems relevant to me is this: <?php $totalPrice = 0; foreach ( $_SESSION["cart"] as $product) { $totalPrice += $product->getPrice(); //<<<LINE 94 ?> The error I get is Fatal error: Call to a member function getPrice() on a non-object in C:\usr\web\shopping_cart.php on line 94 Should $product be a cast to the Product object? class Product { private $productId; private $productName; private $price; public function __construct( $productId, $productName, $price ) { $this->productId = $productId; $this->productName = $productName; $this->price = $price; } public function getPrice() { return $this->price; } //etc. } $i = 0; while($i < 10) { if ($i == 7) { //Do Function } else { $i++ Go back to beginning of loop } //More if statements here. } Hi, I have two variables: $latest_note and $notes. Whenever I update $latest_note, I also want this (and today's date) to be added to $notes, such that $notes becomes a sort of archive of all of the latest notes, listed by date. I tried creating a third variable called $full_notes and saying $full_notes = $latest_note.$notes; ... then when I run my mysql update, I set notes='$full_notes' but it's not working properly. Is there a way to simply add one variable to the beginning of another in the db directly, concatenating the two? Thanks! Here is my current code to display files from the end to beginning : Code: [Select] <?php function func() { $date = date("Y-m-d"); $picarray = array(); $userarray = array(); $handle = opendir ('pqimages/'.$date.'/'); while (false !==($file = readdir($handle))) { if($file != "." && $file != "..") { $picarray[] = "http://blah.com/pqimages/".$date."/".$file.""; $userarray[]= "pqimages/".$date."/".$file.""; } } sort($picarray); sort($userarray); closedir($handle); $json_array = json_encode($picarray); echo $json_array; } func(); ?> How could I change this from end to beginning for ($picarray)? Cheers, George My first post.
I am trying to import images related to a particular listing ID. Currently, I have to enter the number of available photos into a db table, and run the following loop;
<section id="photos">
<?php
$b = $row['PIX'];
for ( $a = 01; $a <= $b; $a++ ) { echo "<a href=\"../imgs/{ $row[ 'ID' ] }-" . { $a } . ".jpg\" ><img src=\"../imgs/{ $row[ 'ID' ] }-" . { $a } . "_tn.jpg\" /></a> " ; } ?> </section> I would like to find a way to import all the images that begin with the $row[ 'ID' ], but without me having to enter/store { $b } (the number of images recorded in the db). How can I accomplish this? _ This is my code: $episodes = mysql_query("SELECT * FROM episode_links WHERE episode_id = '".$episode_id."' AND moderated='1' ORDER BY host ASC"); while ($episode = mysql_fetch_assoc($episodes)) { // code here } and in my host table, I have values like this: Fileserve.com MegaUpload.com Rapidshare.com Torrent And I would like a way to sort this so that only the Fileserve links appear on the top ( the first few results), then all the others. can anyone help me? I keep getting errors that are associated with one-off and one-time occurrences. I want to tell the script to just restart itself from the beginning if it encounters any type of error, whether it by a fatal error, or any other kind. is there a way to do this? Hello guys, im using this code atm and it's working, but the new rows created are put in the end of the table. I want them to stack up from the beginning pushing older rows down. What should i do to make that work? <?php $con = mysql_connect("localhost","*****","*******"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("ananaz_se", $con); $sql="INSERT INTO stuff (adult, namn, url) VALUES ('$_POST[adult]','$_POST[namn]','$_POST[url]')"; if (!mysql_query($sql,$con)) { die('Error: ' . mysql_error()); } echo "1 row added"; mysql_close($con) ?> Hello, I have this XML file I am parsing and I have hit a small formatting issue that I can't seem to get around.
Here is what the the output of the RSS looks like.
<description><![CDATA[<div style='text-align:left;'>Exit ramp closed. <br/><b>Current Status:</b> Open<br/><b>Affected Lanes:</b> Exit Ramp<br/><b>Dates:</b> Wednesday, May 28 - Thursday, May 29<br/><b>Days Closed:</b> <font color='#808080'>S</font><font color='#808080'>M</font><font color='#808080'>T</font><font color='#FF0000'><b>W</b></font><font color='#FF0000'><b>T</b></font><font color='#808080'>F</font><font color='#808080'>S</font> 20:00 PM - 6:00 AM</div>]]></description>Notice at the first is "Exit ramp closed." There is nothing before it but, for some weird reason when I parse it. It is on a new line like so, notice it should be up there with "Incident" but, it is dropped down below it. Incident: Exit ramp closed. Current Status: Open Affected Lanes: Exit Ramp Dates: Wednesday, May 28 - Thursday, May 29 Days Closed: SMTWTFS 20:00 PM - 6:00 AMThis is how it is formated in the td cell.
<td style='{$td2Style}'><strong>Incident:</strong> {$incident_data_desc}</td>\n";
So as you can see above, there is nothing before it that would cause it to break to a new line both in the table or in the RSS.
So how can I remove that first return only is that is on the same line with it and not below it.
I have tried this and a couple of other things like trim with no luck.
$description = $item->description;
$incident_data_desc = str_replace("\r", '', $description );
Note, I only need that first one removed, the others are fine. I can do it but it will remove all the breaks and I only want to remove that first one that is causing the line to be on a new line.
Any suggestions?
-ThanksHi, I've always used PHP code in my websites in a procedural manner as I come from a html/css background. Now that I want to do projects with more complexity I'm thinking I need to approach development in a more Object Oriented fashion. My question is more a theoretical one. I'm creating a User class and I'm not sure on what is the best practise for putting my functions etc. and where to call them. My project will have 2 different users (Admin & End User) so is it correct to say that the User class should encapsulate all the functions of both of these users ? By that I mean create/delete/modify user, login & change password/forgotten password functionality rather than having a seperate Login class Should I only call the database functions within these methods of the user class as opposed to calling them on the php page where the form data is posted ? For example, if a user logins in and when the form data is posted I currently open a connection, validate data, run the query. In an OO approach would I have just one User class method thats relevant to a particular page functionality ? Say, in pseudo code, for handling a login request loginRequest.php Code: [Select] include User class try { create new user User(); User::login(); } catch Exception() and should my User class look something like this class.User.php Code: [Select] include DBase class class User { var name, var email, var password, function validateInput (email, password) { if (!valid input) throw Exception else return true } function login (email, password){ try { database connection validateInput(); sql to see if user exists and login } catch Exception } } Apologies for this being a bit long winded! thanks tmfl I have a table with postcodes in it. At some point some of the codes will be entered with spaces (LA12 5TH) and some without (LA17HU) what i need is a function to check if there is a space, if not - count back 3 characters from the end of the string and insert a space. I don't know which string function to use - looked at pad but that seems to be for either end of string and not the middle - any ideas? I've inherited a website (www.bonniebakerlaw.com) and have found that the previous web developer had left the contact form in quite a shambles. As you can see it attempts to use a Captcha to validate users, but does not in fact work! I can leave the entire form blank (including the captcha) and still get to the "Thank You" page indicating the form was correctly submitted (This does not, in fact, actually generate an email correctly)! So before I delve into "Head First PHP & MySQL" to debug and correct the error, I was wondering if some kind person(s) would be good enough to point me to the relevant sections / documentation highlighting the fundamentals of building this type of form correctly coupled with the use of a Captcha as noted. Some code has been REDACTED to protect the innocent. I won't post the HTML of the form as it's available from the web site and is a fairly simple HTML construct. Form Code: Code: [Select] <?php require_once('recaptchalib.php'); // Get a key from https://www.google.com/recaptcha/admin/create $publickey = "REDACTED PUBLIC KEY"; $privatekey = "REDACTED PRIVATE KEY"; # the response from reCAPTCHA $resp = null; # the error code from reCAPTCHA, if any $error = null; # was there a reCAPTCHA response? if ($_POST["recaptcha_response_field"]) { $resp = recaptcha_check_answer ($privatekey, $_SERVER["REMOTE_ADDR"], $_POST["recaptcha_challenge_field"], $_POST["recaptcha_response_field"]); if ($resp->is_valid) { echo "You got it!"; } else { # set the error code so that we can display it $error = $resp->error; } } echo recaptcha_get_html($publickey, $error); ?> "Thank You" page Code: Code: [Select] <?php $visitor = $_REQUEST['visitor'] ; $visitormail = $_REQUEST['visitormail'] ; $State = $_REQUEST['State:'] ; $Address = $_REQUEST['StreetAddress'] ; $City = $_REQUEST['City:'] ; $Zip = $_REQUEST['Zip:'] ; $Phone = $_REQUEST['Phone:'] ; $Fax = $_REQUEST['Fax:'] ; $Emailed = $_REQUEST['Emailed'] ; $Phoned = $_REQUEST['Phoned'] ; $Faxed = $_REQUEST['Faxed'] ; $Postaled = $_REQUEST['Postaled'] ; $Description = $_REQUEST['IssueDescription'] ; if ($Emailed == "y") { $req1 = " Email \n" ; } if ($Phoned == "y") { $req2 = " Phone \n"; } if ($Faxed == "y") { $req3 = " Fax \n"; } if ($Postaled == "y") { $req4 = " Postal Mail \n"; } $req = $req1 . $req2 . $req3 . $req4 ; $message = "name: $visitor email: $visitormail Address: $Address City: $City State: $State Zip: $Zip Phone: $Phone Fax: $Fax Requested contact by: $req Description: $Description " ; mail("redacted@somedomain.com", "redacted@somedomain.com: contact page", "$message", "From: $visitormail" ) ; ?> Hello, i have two fields. a beginning year and an ending year. How can i make new fields out of the years in between the beginning and ending years. i hope that makes sense. hi... i have a table ... i add and remove data in the table...when i add new record , information add to center of the table ! whats problem? i want add data in first of table. please guide me.thanks
If a user is on Page X, but not logged in, when they log in to my website, I want them to return back to Page X (in this example). To handle this, I am adding this code to the top of each webpage... Code: [Select] // Set current Script Name. $_SESSION['returnToPage'] = $_SERVER['SCRIPT_NAME']; And then as part of my Log In script I have... Code: [Select] // Redirect User. if (isset($_SESSION['returnToPage'])){ header("Location: " . BASE_URL . $_SESSION['returnToPage']); }else{ // Take user to Home Page. header("Location: " . BASE_URL . "index.php"); } What do you think about this approach? Thanks, Debbie Hello First of all i am very weak about OOP and classes in php. I am learning now but i stuck with very silly problem. My codes are below. <?php class myTestClass { function __construct() { $this->OldName("This is Old Name"); } function OldName($VeryOld) { if($VeryOld == "This is Old Name") $this->NewName(); else $VeryOld = "Something Wrong"; return $VeryOld; } function NewName() { echo "This is Brand New Name"; } } $i = new myTestClass(); ?> if i send value to OldName "This is Old Name" then codes works fine. But if i send "This is Old Nameeee" then does not appear anything. what i want to do is print "Something Wrong" text if i enter different value. I have no idea what return do and how it do? How to retrieve/print "Something Wrong"? i can do that with echo but i want to transfer result of return to another function. Really appreciate for any help/idea. Hey all. My site has a config database table that has a column showlogin to set whether or not login functionality is enabled. I'm playing around with MySQLi, Classes, and Returns. My return is always 1. Where am I going wrong? test.php <?php // Start Session session_start(); // Production Settings ini_set('display_errors', 1); mysqli_report(MYSQLI_REPORT_ALL); include 'db.php'; $mysqli = new mysqli($host, $user, $pass, $db); class styles { function showlogin($show) { global $mysqli; $select = $mysqli->query("SELECT showlogin FROM config LIMIT 1"); $value = $select->fetch_object(); if ($value->showlogin = 1) { return 1; } return 0; } } $login = new styles(); echo $login->showlogin($show); ?> Hi Everyone,
My name is Raoul Grosser, live in The Netherlands.
I'm a front/backend developer working with AngularJS and Bootstrap and Symphone2.
I've been writing PHP code for over 4 years now my focus is on opensource projects.
If you have any question, please let me know!
return (int) $value VS return $value
What is the purpose of using int in a bracket? return (int) $value
Which is the best and safest method?
Thank you
