PHP - Remove ' Mark In Php
Im trying to rermove ' symbol from a string.
Code: [Select] $string2 = str_replace(" ' ", " . ", $string1); give errors How else could i do this? Similar TutorialsI made a template class recently and the only problem I'm having with it is that when I pull the HTML through if I add double quotes anywhere it breaks the code. I understand why its breaking sorta but I can't figure out how to fix it. Code: (HTML) [Select] <html> <head> </head> <body> <p id='Element'>"Something in quotes"</p> </body> </html> Code: (PHP) [Select] $string = $template->myMethod();//Returns the html in a string eval("\$HTML = \"$string\";"); //The error happens during the evaluation here echo($HTML); The string breaks with double quotes during the eval method and I've tried replacing the " mark with \" by using str_replace but i haven't been able to get it to work. Thanks for your replies I imagine there are lots of ways to answer this question, so I just want people's opinions as to the best way (if there is one). I have code with a basic form that submits data to a MySQL database. So when someone submits data the first time, I "clean it up" by doing... Code: [Select] $_POST['data'] = trim(mysql_prep($_POST['data'])); .. and then submit that info into a "varchar" mySQL field. Then if the user comes back to edit it, the form comes up and the data they previously entered is pulled into the field this way (I'm leaving out the MySQL to pull the data, obviously)... Code: [Select] <input type="text" name="field" value="<?php echo $data;?>"> The problem is that if someone entered this originally... Code: [Select] Here is "some" data with apostrophes ...Then when I echo that back into the value of the text field, it would only show... Code: [Select] Here is "...and then cuts off because the quotation mark in the data conflicted with the quotation mark after value= Is htmlentities the answer here, or is there some other/better way? FYI... Code: [Select] function mysql_prep($value) { $magic_quotes_active = get_magic_quotes_gpc(); $new_enough_php = function_exists("mysql_real_escape_string") ; //i.e. PHP >= v4.3.0 if($new_enough_php) { //PHP v4.3.0 or higher //undo any magic quote effects so mysql_real_escape_string can do the work if($magic_quotes_active) { $value = stripslashes($value) ;} $value = mysql_real_escape_string($value); } else { //before php v4.3.0 // if magic quotes aren;t already on then add slashes manually if(!magic_quotes_active) { $value = addslashes($value); } // if magic quotes are active, then the slashes already exist } return $value; } So I really don't think I need to paste the code but Code: [Select] <?php session_start(); ?> <?php $new_thread_page_path = 'general_discussion_threads/' . $_POST['thread_title'] .

Then it makes a new row and 3 cells in the home pages thread table that link to the page say who made it and what time they made it. Now it all works PERFECT (Im suprised how perfect on the first try actually) except for 1 tiny flaw which i think might be php not me but im not sure. The fwrite creates a new file but if the input contains any question marks (?) the link will work but no file will be created. For everyother character on teh standard keyboard its fine but not the question mark. What gives? thanks yall! MOD EDIT: <code></code> tags changed to proper [code] . . . [/code] BBCode tags. Hello, I found this great free php calandar script here "" by Xu and Alessandro, and I'm trying to modify the code to mark several dates(birthdays YYYY-mm-dd) from a date column in a sql database. I've played around with the _showDay() method but I can't seem to get it working.. I've also tried to create a _showBirthday() method to modify the css as well but with no luck. What I'm trying to do is loop through the database to mark the respective dates on the calendar, and have a href to display a new page with the person's name when I click the specific date. Can anyone help with this. Thanks in advance! I have a notification system that notifies users of new comments, inside the email I have images, some of the logo, some of different people, everything shows up fine on my computer (yahoo email), however in the iPhones email application no images show up, there are just the blue squares with the question marks in them. I'm not sure what I'm missing. Code: [Select] $from = "Kithell <notifications@kithell.com>"; $headers = "From:" . $from ."\r\n"; $headers .= 'MIME-Version: 1.0' .

Can anyone help please Thanks i need to make it so it removes the \ like this <iframe src=\"http://www.rockstargames.com/videos/embed/8001\" width=\"640\" height=\"360\" frameBorder=\"0\" scrolling=\"no\"></iframe> How do i remove with %20%20%20 from a pictures name? Silly question but my pictures wont show because of the %20%20%20 in the picturename. I'm a noob, tring to reverse engineer some current code. This code is grabbing the current URL: <?php function curPageURL() { $pageURL = 'http'; if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";} $pageURL .= "://"; if ($_SERVER["SERVER_PORT"] != "80") { $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"]; } else { $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]; } return $pageURL; } ?> This form is adding "&limit=50" to the URL, to show 25, 50 or 100 results per page: Code: [Select] <form> <select name="link"> <option <? echo "$select25" ?> value="<? echo curPageURL(); ?>&limit=25">25 records per page</option> <option <? echo "$select50" ?> value="<? echo curPageURL(); ?>&limit=50">50 records per page</option> <option <? echo "$select100" ?> value="<? echo curPageURL(); ?>&limit=100">100 records per page</option> </select> </form> The problem is here (I think). This is supposed to flush the old limit before requesting a new one... but right now, I'm getting another one tacked on with each new request: www.website.com/members?sub[]=math&sub[]=science&lev[]=middleschool&limit=25 www.website.com/members?sub[]=math&sub[]=science&lev[]=middleschool&limit=25&limit=50 www.website.com/members?sub[]=math&sub[]=science&lev[]=middleschool&limit=25&limit=50&limit=100 <?php //remove any old limit from query $tmp = array(); foreach ($_GET as $fld => $val) if ($fld != 'limit') $tmp[] = $fld . '=' . $val; $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"] . '?' . implode('&',$tmp); ?> Any ideas? Thanks. ~Wayne I am passing variable to a PHP page and was wondering if there is a way to clean these varilabes from the url once i pull the information out of it. For example my URL is "http://www.MYURL.com/index.php?var1=TEST1&var2=TEST2" Now what i want to be able to do is when someone visits the above link i want to assign var1 and var2 to a variable and then remove then from the addressbar so the vistor can only see the base URL (http://www.MYURL.com) in the address bar but i get my variables Anyone know what i can use??? Anyone know how i can remove a querystring from url. Example URL: http://www.mysite.com/?id=1 I am writing a script that needs to read in the ID from the URL. But once have got the information i would like to remove it from the URL and just display http://www.mysite.com but still be able to use the ID to query my database. Any ideas??? Hey, i got this code which takes info from mysql: while ($row= mysql_fetch_array($result)) { $title = $row["alertid"]; $title2 = $row["alerttext"]; $title3 = $row["alertdate"]; $bla = "{\"alertid\":\"$title\",\"alerttext\":\"$title2\",\"alertdate\":\"$title3\"},"; echo "$bla"; } it is displayed like this: [{"alertid":"1","alerttext":"text1","alertdate":"date1"},{"alertid":"2","alerttext":"text2","alertdate":"date2"},{"alertid":"3","alerttext":"text3","alertdate":"date3"},] I wanted to ask, how can I remove the last comma, after date3"}, but keep other commas..? This is probably very obvious but i gots stuck. I want to to display a list of the members then you select the member and it deletes the member. I do not get a message saying it failed, it just doesn't delete the member. Removemember.php: Code: [Select] <form action='removemember_complete.php' method='POST'> <label>Name:</label> <select name="memberid"> <?php $con = mysql_connect("localhost","slay2day_User","slay2day"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("slay2day_database",$con); $sqlquery="SELECT * FROM `members` Order By name"; $result=mysql_query($sqlquery,$con); while($row=mysql_fetch_array($result)) { echo "<option value='".$row['id']."'>".$row['name']."</option>"; } ?> </select> <br> <input type="submit" value="Remove" /> </form> removemember_complete.php: Code: [Select] <?php $name=$_POST['name']; $con = mysql_connect("localhost","slay2day_User","slay2day"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("slay2day_database",$con); $sql="DELETE FROM members WHERE name = '$name'"; if(mysql_query($sql,$con)) { echo 'Member Removed.<br /><a href="../index.php">Return To Points List</a><br /><a href="removemember.php">Remove More Members</a>'; } else { die('Could not submit: ' . mysql_error()); } mysql_close($con); ?> Thanks in advance. I'm currently have this code (part of code):
if (strlen($trimmed['title']) > 3 && strlen($trimmed['title']) < 200) {
$title = mysqli_real_escape_string($dbc, $trimmed['title']);
} else {
echo '<div class="alert alert-danger" id="alerta3">
<button type="button" class="close" data-dismiss="alert">×</button>
<center><p>Error</p></center>
</div>';
$errors=true;
}
if (strlen($trimmed['description']) > 3 && strlen($trimmed['description']) < 4000) {
$description = mysqli_real_escape_string($dbc, $trimmed['description']);
} else {
echo '<div class="alert alert-danger" id="alerta4">
<button type="button" class="close" data-dismiss="alert">×</button>
<center><p>Error</p></center>
</div>';
$errors=true;
}
What should i modify to avoid texts with /n/r?
Thanks
Please can someone advise how I remove the | characters from a string? I tried the following but get errors that... Warning: preg_replace() [function.preg-replace]: No ending delimiter '|' Code: [Select] $value = preg_replace("|", "", $value); I need permanent redirect. Example url: example.com/something/more/more/1 I always have /something/, so it would be awsome if you could remove /1 only from urls where are /something/ for first path argument. There can be any number of different url segments in between /something/ and /1, those should be kept there, just /1 should be removed. So the redirect path of the example url should be example.com/something/more/more How can I do this? Not sure if this is possible. What I am trying to do is remove a section of text a user posts. ie: go to this url: http://url.com or http://this.domain.org I already have it to strip they <a href="whatever but not sure if I can do the other. Any help would be appreciated. Thanks Hi All, I'm sure there is an easy solution for this but I am unable to find it. I am new to PHP and after a little help... the via data is stored in a database in this format... |51.105166,-1.695971|51.011055,-2.1068|50.945233,-2.617664|||| I'm trying to find a way of loosing the last comma if there are 1 or more entries, any ideas guys. What I'm getting is : Code: [Select] var points = [{location: '51.105166,-1.695971'},{location: '51.105166,-1.695971'},]; What I'm after is: Code: [Select] var points = [{location: '51.105166,-1.695971'},{location: '51.105166,-1.695971'}]; Code: [Select] <?php if($via != null){ echo "var points = ["; foreach($via as $point){ if($point != ""){ echo "{location:"; echo " '".$point."'"; echo "},"; } } echo "];\n"; } ?> My current code (which works): Code: [Select] <?php $body = explode("\n", $body); $body = array_slice($body, 3); $body = implode("\n", $body); ?> Is there a better way of doing this, so I dont have to explode and implode an array just to accomplish this? hi phpfreaks I am trying to remove the get variables from my url. the code below works if I echo it out but to try to modify the $_server variable it will not work. Any ideas? Code: [Select] $current_url = explode('?',$_SERVER["REQUEST_URI"]); $_SERVER["REQUEST_URI"]= $current_url[0]; echo $current_url[0]."<br>"; |
