PHP - Some Kind Of Replace
I have this html tag <navigation></navigation>. I want to find any and all references to <navigation></navigation>, retrieve the int value thats between the <navigation>3</navigation> (in this case the number 3), run an sql query and return a record where the id is the value between <navigation>3</navigation> (again in this case 3) and replace the entire tag with whatever was returned from the sql query.
note: there could be more than one navigation tag within my string. plus a bunch of other html. i want to keep all the other and find, build, and replace new text where the navigation tag is. Similar TutorialsIm dealing with html links in a database where I need to execute a small piece of php code. Well mysql doesnt execute php code thats held in a table. The easiest way for me to do this is just add the links without the code, & set up a function that will replace anything I set to for example in my case a link lookin like this: http://mysite.com/index.php?page=offers&blah=blah&sid= needs to look like this; http://mysite.com/index.php?page=offers&blah=blah&sid=<?php echo $_SESSION['login']; ?> so I would need a function like <?php $replace('sid=','sid=<?php echo $_SESSION['login'];?> ?> something like that. And I know its possible & I could create a function like this but honestly right now I am so tired after working 12 hours im lazy dont want to think to hard while I know there are a lot of people out there that have a function like this already. If you dont have one & dont feel like writing one for me could you atleast point me in the right direction so I dont have to think to hard?! Thanks!! The situation is that I have a large string with some identifiers to say "replace me" with something else. My goal is to replace the values, but if one replacement includes one of the other keys, I don't want to replace it.
For example:
<?php $str = 'some blob ~abc~ followed by ~def~'; $arr_orig = array( '~abc~', '~def~' ); $arr_new = array( 'value~def~', 'blah' ); echo str_replace( $arr_orig, $arr_new, $str ); ?>This will echo: some blob valueblah followed by blah But that's not what I'm trying to accomplish. Basically, I want ~abc~ to be replaced with the literal: value~def~ and for the ~def~ that happens to be part of that string to NOT be replaced. I hope what I'm asking is clear. Basically, preg_replace/str_replace with arrays seems no different than just doing a FOR loop and replacing ~abc~ and then ~def~. But that's not what I need. I'm hoping that if ~abc~ is replaced with text that happens to be another identifier -- ~def~, ~xyz~, whatever -- that this already replaced text is not again replaced. Is there a built-in function to do something like this? If not, should I just parse the whole string and count characters or something? Seems like a pain (and slow!) Hi i wrote a find and replace code but my code replace last value of array and skip the first, second.... values in the array. Please give me an idea because i stack with this code. Regards $KeyWord = explode("\n", $RowGetWords['KEYWORDS']); $Replace = explode("\n", $RowGetWords['ReplaceTo']); for($i=0; $i<count($KeyWord); $i++){ $pattern = $KeyWord[$i]; $replace = "<a href=\"" .$URL. "\" target=\"_blank\" >" .$Replace[$i]. "</a>"; $html = str_replace($pattern, $replace, $Row['MessageBody']); } Check below website http://www.emirates.com/ae/english/index.aspx In flight search what kind of AJAX suggestion they have used? if i search "dxb" or "Dubai" "united arab emirates" after user choose option it change the text with system defaul for that airport which is "Dubai (DXB)" I am making same kind of website this is client requirement. Thanks in advance. Hi, You may noticed that i've posted before and closed them. It was too hard. I've been searching around for something else and i found it. But it's not quite perfect. What i want to do is make thumbnails smaller (i can do that on my own) but displaying the bigger picture above the thumbnails. And aligning the thumbnails next to each other. So how do i do that? The current code: <?php $result = mysql_query("SELECT reference FROM user_photos WHERE`profile_id`='".$row['id']."'"); while ($row2 = mysql_fetch_array($result, MYSQL_ASSOC)) { echo "<a href=\"".$_GET['username']."/pics/".$row2['reference']."\"> <img src=\"".$_GET['username']."/pics/thumbs/".$row2['reference']."\"></a><br/><br/>"; } } ?> The files are refering to the mysql in reference but are actually in a subfolder with the username on the server. I hope somebody wants to help me, Best regards, Martijn (the netherlands) Well, In my DB i have user items as follows: Code: [Select] 13,12,11,9,27,15,16,22,21,23,24,26,29,30,31,32,33 Each ID is a user item that has been imploded to be sent to the DB. Well, I', trying to take them out of the DB now, and I'm having a small problem turning them back into integers. Here's what I've done. Code: [Select] $items = explode(",", $row['user_item_id']);So I get: Code: [Select] 0 => string '13' (length=2) 1 => string '12' (length=2) 2 => string '11' (length=2) 3 => string '9' (length=1) 4 => string '27' (length=2) 5 => string '15' (length=2) 6 => string '16' (length=2) 7 => string '22' (length=2) 8 => string '21' (length=2) 9 => string '23' (length=2) 10 => string '24' (length=2) 11 => string '26' (length=2) 12 => string '29' (length=2) 13 => string '30' (length=2) 14 => string '31' (length=2) 15 => string '32' (length=2) 16 => string '33' (length=2) Then I do this: Code: [Select] foreach($items as $item){ var_dump($item); $sql = 'SELECT * FROM `MYTABLE` WHERE item_tab = '.$tab_id.' AND item_id = '.$item.' AND item_pose =0'; } and get this: Code: [Select] string '13' (length=2) string '12' (length=2) string '11' (length=2) string '9' (length=1) string '27' (length=2) string '15' (length=2) string '16' (length=2) string '22' (length=2) string '21' (length=2) string '23' (length=2) string '24' (length=2) string '26' (length=2) string '29' (length=2) string '30' (length=2) string '31' (length=2) string '32' (length=2) string '33' (length=2) Now, this works how I want it to except, I want a integer value not a string. What would be the best way to approach this? I have multiple \n in a string, and I need to replace it with <br />. How do I go about doing this? Preg replace? Hi, I'm pretty new to PHP, and I'm trying to write my own encoding/decoding script (not with base_64). I'd like to replace like all A's with B's, all B's with C's, C's with D's, and so on. How would I do this? Here's an example: String #1: "ABCDEFG" string #1 goes through my encryption string #2 (output): "BCDEFGH". How would I go about doing this? Thanks. I retrieve urls that have the following path $url=http://cdn.test1.com $url=http://cdn.test2.com and so on... i want to to do a string replace such that it displays http://test.com,http://test2.com and son without the cdn part. Will the following work for all cases? Code: [Select] $url=str_replace("cdn.","",$url); User can edit a post. I need to replace the html '<br/>' element to newline character ('\n') . When a user will edit a post he/she will not see the '<br/>'. How can i do this with php ? ok so I have an string with data that I need to be replaced with contents from an array. I need the occurance position replace with the index of the array. example Code: [Select] //here is the setup $string = "testing %s one %d %s"; array('this',1,'three'); //here is the result testing this one 2 three the problem I am having is because the %s can occur more than once I cant use str_replace. I am working on a solution with substr_replace but was wondering if anyone had any suggestions on how to do this. When I replace it I also need to run the value through a function so keep that in mind. Also the replace's are stored in an array so they need to be looped through as well. Code: [Select] $replaces = array('%s'=>'func_one','%d'=>'func_two'); Any help is appreciated. How does wordpress and other similar CMS/applications replace their div elements? For example, if you view the source code of a wordpress site, you will only see: Quote <div id="header"></div> Where, the above code is clearing being switched out for "header.php". How is this done? I believe it's php and jquery, but I would be wrong. Thanks! Hello, I'm trying to convert a paragraph of text which is already html formatted. I wish to find keywords, such as, 'PHP', which are contained in the paragraph, and replace them with a link, for example <a href="http:/www...">PHP</a> str_replace('PHP', '<A href=""....">PHP</a>', $content); My problem arises when some of these keywords are already contained in a link, so say, visit PHP website, is all one link, so str_replace would simply convert the PHP in this string, to two links for one single word. Code: [Select] <a href="">visit <A href=""....">PHP</a> website</a>How could this problem be resolved? Thanks Hello: I have a quick question. I am currently using the following code to replace an apostrophe and quote marks when inserting and updating a database record: Code: [Select] $myPageContent = mysql_real_escape_string(str_replace("'", "'", $_POST['myPageContent'])); $myPageContent = mysql_real_escape_string(str_replace("", """, $_POST['myPageContent'])); My question is - how can I modify it so I only need to use one line. Like (but this does not work): Code: [Select] $myPageContent = mysql_real_escape_string(str_replace("'", "'", "", """, $_POST['myPageContent'])); It seems to me that the way I am currently doing it might be POSTing the data twice? Thanks! alright, is this the correct format for a REPLACE INTO? if not what do i need to change.......it isn't working...... Code: [Select] $sql = "REPLACE INTO Events (name, event, eventid, userid, title1, title2, title3, title4, title5, title6, title7, title8, email) VALUES('$name','$event','$eventid','$userid','$title1','$title2','$title3','$title4','$title5','$title6','$title7','$title8', '$email')"; $rs = mysql_query($sql) or die ("Problem with the query: $sql<br>" . mysql_error()); basically what i am trying to do is replace the <a href="whatever.com"> with <a href="whatever.com" onclick = "if (! confirm("Continue?")) return false;"> so that when the user clicks the url in a message the box pops up first then redirects them to the url if they click confirm. However i am getting the following error: Code: [Select] Warning: preg_replace() [function.preg-replace]: Compilation failed: reference to non-existent subpattern at offset 11 here is the code i used. $message_content = $content_info['message_content']; $pattern='<a href="\\1">'; $replace='<a href="\\1" onclick = "if (! confirm("Continue?")) return false;">'; $message_content = preg_replace($pattern, $replace, $message_content); echo $message_content; Anyone know where i went wrong? I have a site that allows members to create pages. These pages consist of small sections some of which HTML can be entered. To keep visitors from straying away from the site, any outside urls are brought up in a modal window. Using inline attributes, a class has to be created (or added to), and the title tag requires some special characters. I can probably get around this by inserting an onclick or something, but there must be a way to replace attributes, and I am at a loss. The text segments are stored in a database. What I want to do is change the <a> tag attributes as the page is created. So I have a segment of text "$TheText" and I want to change or replace the attribute values. For instance, If $TheText contains an 'a' tag that looks like this: Code: [Select] <a class="MyClass" title="Godzilla" href="http://www.godzillaslair.com">Godzilla</a>I would want to change it to Code: [Select] <a class="MyClass Lightview" title="Godzilla :: {Lightview's parameters}">Godzilla</a>Or even just replace the attributes entirely, so it would look like Code: [Select] <a class="Lightview" title="{Inserted Title} :: {Lightview's parameters}">Godzilla</a> In other words, just replacing the attribute values. Of course, I need to see if the attributes exist. I know how to do that and how to get their values. But all that tells me is that I have an 'a' tag in the text with those values for those attributes. I cannot, for example, then do a str_replace in the first example, because there may be another tag in the text with the "MyClass" class. I can iterate character by character between <a and </a> but there must be a better way. I'm no good at regex, so I haven't even attempted that. Any suggestions would certainly be appreciated. Hello again. I use echo "Rating:".$json['Rating]."/10"; and get in return: 7.5/10 - it's ok. But I want to replace 7.5 with 75.png (image), 6.3 with 63.png, 9.4 with 94.png... hope u understand. Know someone how I can do this? Thanks. Here is my code Code: [Select] if (isset($_GET['hide'])){ $id = intval($_GET['hide']); $explode = explode(",", $_COOKIE['hide']); if (in_array($id, $explode)) { } setcookie('hide', ''.$id.'',time()+32000000); header('Location: index.php'); exit; } My Explanation: If somone clicks ?hide=2 It will add the cookie hide, and the value to 2. Now, if somone clicks ?hide=1, I need it to add 2,1 how is that possible? Then if the in_array is correct, (Means if the value of the cookie is 2 and they clicked ?hide=2) how do I take that number "2" out of the it (Remove it) and make a new array that will be inserted to my $id variable? how can i find reference to something like this "navigationID=3" or "navigationID=44" within a string and then re write it to become something like this "/en/content/3/Link_Name"? there could be more than one reference within the string and the integer val (ie 3 and or 44) will not be known. Any help with this would be greatly appreciated. |
