PHP - Prevent A Space (beginning, Middle Or End) Charater In A String With Regex
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.
Edited by terungwa, 25 October 2014 - 12:50 PM. Similar TutorialsThe 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, $reason ) ); } } } else { return null; } } The basic layout here is this: |inputbox||radio list| But I want: |inputbox| |radio list| Is this the correct syntax to check for an optional Middle Initial... Quote if (preg_match('/^?[A-Z]$/i', $_POST['middleInitial'])){ Thanks, Debbie Hello, I have this XML file I am parsing and I have hit a small formatting issue that I can't seem to get around.
Here is what the the output of the RSS looks like.
<description><![CDATA[<div style='text-align:left;'>Exit ramp closed. <br/><b>Current Status:</b> Open<br/><b>Affected Lanes:</b> Exit Ramp<br/><b>Dates:</b> Wednesday, May 28 - Thursday, May 29<br/><b>Days Closed:</b> <font color='#808080'>S</font><font color='#808080'>M</font><font color='#808080'>T</font><font color='#FF0000'><b>W</b></font><font color='#FF0000'><b>T</b></font><font color='#808080'>F</font><font color='#808080'>S</font> 20:00 PM - 6:00 AM</div>]]></description>Notice at the first is "Exit ramp closed." There is nothing before it but, for some weird reason when I parse it. It is on a new line like so, notice it should be up there with "Incident" but, it is dropped down below it. Incident: Exit ramp closed. Current Status: Open Affected Lanes: Exit Ramp Dates: Wednesday, May 28 - Thursday, May 29 Days Closed: SMTWTFS 20:00 PM - 6:00 AMThis is how it is formated in the td cell.
<td style='{$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", '', $description );
Note, I only need that first one removed, the others are fine. I can do it but it will remove all the breaks and I only want to remove that first one that is causing the line to be on a new line.
Any suggestions?
-Thankshey guys im trying to find a string inside a string which could be made up of different things eg... {$test}, {$test1}, {$test2} etc (but the varable inside could be called anything hence maybe using regex im not sure?) is this possible?...i hope you guys understand....thanks How do I make sure that SPACES are allow in a regular expression like this... Code: [Select] if (preg_match('/^[A-Z0-9#&\',.-]{2,30}$/i', $_POST['address1'])){ Thanks, Debbie 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 am trying to figure out how to have an if statement in the middle of strings I am trying to concatenate. I have a from that has a address1 and address2, where address2 often does not exist. So I want to only add that line if there is actually content. I was trying something like the following, but that is giving me an error. I am pretty new to php, so I can't seem figure it out. Any help would be greatly appreciated. Code: [Select] "<p><strong>Address 1: </strong><br>" . $address1 . "<br>" if ( isset($address2) ) { echo . $address2 . "<br>" } . $city . ", " . $state . " " . $zip . "</p>" How could I split a string in half but not in the middle of a word? $information = "This is the string of text, however at some point in the sentence a word may get split in half."; $cut = round(strlen($information)/2); ///where to cut (50%) $split1 = substr($information, 0, $cut); //first half $split2 = substr($information, $cut); // second half This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=345658.0 I have a field that is 30 chars max, and I have the code checking if the string is empty upon submit, though if someone were to make that field spaces only, it will allow it, and run the query and insert the data. if (strlen($_POST['title']) <= (($userhandler->getRights() == 2) ? 100000 : 30) && strlen($_POST['message']) <= (($userhandler->getRights() == 2) ? 100000 : 2000) && !empty($_POST['title']) && !empty($_POST['message']) && $userhandler->getRights() >= 0) { Hi Guys and Girls, Long time lurker, first time poster!

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? _ 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 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! 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) ?> 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? Hi, 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 |
