PHP - Href Calling Php Function W/ Parameters
OK, in my html file, I have "${uri}" which is a directory/filename. A link (href) is created directly from "${uri}" that opens the file when clicked. This works great.
<dd><a href="${uri}">${uri}</a> (${size} bytes)<br><br></dd> Now, I want to also add the ability to explor the directoy. So I want to add another link (href) with the directory only include in "${uri}". For example, if "${uri}" = '/this/is/the/directory/and/thefile.txt', I want an href w/ '/this/is/the/directory/and' I created the file dir.php w/ the following <?php function giveme_dir_only( $a ) { $mydir = dirname($a ); return $mydir; } ?> Now, how do I add this to my html/href command. There is no reason to run the dir.php until the user actually clicks on the link, eh? <dd><a href="xxxx">"xxxx"</a> <br><br></dd> Thanks in advance for the help! Similar TutorialsI am making a function it returns one thing, but I would the like to put something into a variable to use outside the function. for example, the third parameter in preg_match() sets a variable that you can then use later in your code, how can I create a parameter like that? This thread is about what you can and cannot call Variables and Parameters in a Function... I have this query which returns 1 or 2 for $gender... Code: [Select] // Check # of Records Returned. if (mysqli_stmt_num_rows($stmt1)==1){ // Member was Found. // Bind result-set to variables. mysqli_stmt_bind_result($stmt1, $firstName, $username, $photoName, $photoLabel, $gender, $birthYear, $location, $occupation, $interests, $aboutMe); And here is my Function... Code: [Select] function displayGender($gender){ if ($gender == 1){ $gender = 'Male'; }elseif ($gender == 2){ $gender = 'Female'; }else{ $gender = ''; } return $gender; }//End of displayGender Questions: 1.) Is it a problem having $gender as both my Parameter and Argument? 2.) Is it a problem renaming $gender inside the Function like I do? 3.) Is it a problem returning $gender like I do? Thanks, Debbie Question 1) Is the only and proper way to call a parent function "parent::function()"? Are there other/better ways from within a child function? Question 2) What are the deciding factors for when to make a function or attribute static? How do you make that decision? Assuming 5.3... Thanks. I need to call usort from a class function, and I'm puzzled about how to define the comparison function. I've tried to define the comparison function in the same class, but I can't get usort to call it. I found one hint that it will work if I make the comparison function static, but I tried that, and it didn't work for me. If I define the comparison function outside the class, it won't have access to object properties that it needs to operate. The only solution I can think of is to define the comparison function outside the class and put the object properties it needs in globals. Is there a cleaner way to do this? Hello, I have created a webpage that essentially generates an sql query and then puts the results into a table that is displayed. On one of the columns in this displayed table, I want to allow the user to click on each of the values which will in turn execute a php function. I have the hyperlink working but this is to a separate page. What I actually need to do is firstly - just ran a php function that will create a new table beneath the currently displayed one. Secondly, once this is achieved, I need to pass some value to the function so that the generated table is dependent on the value that was clicked. I've tried a few things and researched but I am struggling. I am a beginner. Any help would be greatly appreciated. Here is an extract of the code used for inputting data into the original table - showValuesSR is the function name <?php while (!$rsMetrics->EOF) { ?> <tr> <?php for ($x=0; $x<$numberOfFields; $x++) { if ($fieldNames[$x] == "Values_SR"){ ?> <td><a href= ?showValuesSR><?php echo $rsMetrics->fields[$fieldNames[$x]]->Value?></a></td> <?php } else{ ?> <td><?php echo $rsMetrics->fields[$fieldNames[$x]]->Value?></td> <?php } } ?> </tr> <?php $rsMetrics->MoveNext(); } ?> </table> <?php function showValuesSR(){ ?> <table border="0" cellpadding="5" width="100%"> <tr><td background="../images/table_toolbar_bkg.gif" align="center"><font color="Blue" face="verdana" size="2"><strong>function working</strong></td></tr> </table> <?php } ?> I am calling CURL and trying to do a POST request with parameters: Code: [Select] $curl = curl_init(); curl_setopt($curl, CURLOPT_HTTPHEADER, Array("Accept: application/json", "Content-Type: application/json")); curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 15); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true); curl_setopt($curl, CURLOPT_USERAGENT, "curl 7.23.1 (x86_64-unknown-linux-gnu)"); curl_setopt($curl, CURLOPT_USERPWD, "username:password"); curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); curl_setopt($curl, CURLOPT_URL, "https://www.mydomain.com/route"); curl_setopt($curl, CURLOPT_POST, true); curl_setopt($curl, CURLOPT_POSTFIELDS, "key1=blah1&key2=blah2"); return curl_exec(curl); The problem, inside the request at http://www.mydomain.com/route I am not seeing any POST parameters passed. I.E. Code: [Select] print_r($_POST); Code: [Select] Array ( ) Should have key1=blah1 and key2=blah2. Any ideas? Hi, I got a little problem with calling a PHP function from a href. I got my site all set up, and am calling the function like this: Code: [Select] <?php echo '<a href="'.changeRecentPosts().'" class="image">' ?> This does indeed work, but it calls the function every time I refresh my page.. Which isn't the effect I was trying to achieve. I tried to change it to : Code: [Select] <?php echo '<a href="#" onClick="'.changeRecentPosts().'" class="image">' ?> But that didn't work either. It also seems it only calls it when I refresh my page, but never when I click it (I guess because PHP is handeled before HTML or something similar?). If you can think of any way (even in AJAX, or whatever other language...) feel free to, I think I can figure it all out. Thank you! I am using simple machines forum, and by placing a link to ssi.php in the top of my php page Code: [Select] <?php require_once('/forum/SSI.php');?>I am able to use some ssi functions. My problem is calling another function from within a function. My first function is this: Code: [Select] <?php $allowed_groups = array(1,5); $can_see = FALSE; foreach ($allowed_groups as $allowed) if (in_array($allowed, $user_info['groups'])) { $can_see = TRUE; break; } if ($can_see) { echo ' <div> this is text that i want certain groups to see </div>'; } else { //message or section to show if they are not allowed. echo 'this is text that i dont want certain groups to see'; } ?> This is my second function: Code: [Select] <?php ssi_welcome(); ?> I want to put the second function inside the first function, like so: Code: [Select] if ($can_see) { echo ' <div> <?php ssi_welcome(); ?> </div>'; this just gives me the "<?php ssi_welcome(); ?>" displayed on the actual site, it is not calling the separate function. I have tried different approaches, e.g. $function ssi_welcome; but all it does is display this as text as well.. Please can some one point me in the right direction. Thank you Whenever I want to use AJAX (using jQuery) I store the PHP code in a seperate file and then send an retrieve data from that file using AJAX. However I was wondering if you can just call a PHP function. Then it would save me having to put each function in a seperate file? Thanks for any help.

Hi, I was looking around the web for a image resizer script and I came across this one. http://www.scriptol.com/scripts/thumbnail-maker.php The weird thing is, it says to use this syntax to get it to work php resizer.php -j myimage.png Well.. I don't seem to understand how that makes it work, Normally I would run a php script by looking for it's main function and running it like: mainfunction(); Maybe I'm interpreting it wrong, but how is this script suppose to run? Hi all! First off, sorry if this question is a completely dumb one but i'm really new to PHP. I'll paste the code to start with... function getReasons ($id) { global $link; $rst = mysql_query('SELECT r.name as reason FROM entries_feedback_comments as f LEFT JOIN reasons as r ON r.id = f.reason_id WHERE f.feedback_id ='. $id, $link); while ($row = mysql_fetch_assoc($rst)) { echo $row['reason']; } } later on in the code.... inside a table structure i do this... echo '<tr class="' . ($y?'even':'odd') . '">'; echo '<td colspan="10" class="freetext">'.getReasons($row['id']).'</td>'; echo '</tr>'; echo '<tr class="' . ($y?'even':'odd') . '">'; echo '<td colspan="10" class="freetext">'.$row["freetype"].'</td>'; echo '</tr>'; (I have left put the "freetype" bit of code in to show you that it works with this row but not with the function). Basically, what I see is the result of the function outside of the table itself rather than in the table row. Is there a reason for this? Does a function have to be put in specific places in the code? Thank you for your help. Sam Code: [Select] <?php class My { public function disp() { echo "ehllo"; } } ?> <html> <head> <script type="text/javascript"> function displaymessage() { document.write(My.disp()); } </script> </head> <body> <form> <input type="button" value="Click me!" onclick="displaymessage()" /> </form> </body> </html> HEllo I wanted to know wheter php function can be call in js functions. Please Help. Hello, I am a newbie to php. I am trying to figure out how to call a function when a user clicks submit on a form. I have a sample script that I am writing where the user inputs there name, address, etc.. and then clicks submit and it inserts into the mysql database. I have successfully done this with form action to my adduser.php file, but I would rather have a single function file with adduser, delete a user, edit a user, etc.. here is my form <form action="includes/customersfunctions.php?add" method="post"> name: <input type="text" name="name" /><br /> address: <input type="text" name="address" /><br /> city: <input type="text" name="city" /><br /> state: <input type="text" name="state" /><br /> zip: <input type="text" name="zip" /><br /> <input type="submit" /> </form> Here is my function <?php function add() { include("config.php"); mysql_query("INSERT INTO customers (name,address,city,state,zip) VALUES ('name','address','city','state','zip') ") or die(mysql_error()); echo "added"; mysql_close($con); } ?> The function will have delete, update, etc.. later Thanks for your help in advance! Trying to run this function so it displays the generated image in a table cell - Code: [Select] <?php function imgsecuregen($size = 6){ $width = 11*$size; $height = 25; $string = ""; for($i = 1; $i <= $size; $i++){ $string .= rand (0,9).""; } // for $im = ImageCreate($width, $height); $bg = imagecolorallocate($im, 102, 102, 102); // background $black = imagecolorallocate($im, 0, 255, 0); // text $grey = imagecolorallocate($im, 102, 102, 102); // border imagerectangle($im,0, 0, $width-1, $height-1, $grey); imagestring($im, 5, $size, 5, $string, $black); imagepng($im); imagedestroy($im); } imgsecuregen(8); // string length ?> Works if I load it directly, but not in a <td>. I've created a function getsub(). The idea is that this function contains a query that grabs records from the categories table, using the $row['cat_id'] that I pass to it from within an existing while ($row=mysql_fetch_assoc($res)) loop. Heres the function: function getsub($rowid,$catsort) { global $system, $LANGUAGES, $subres; $subquery = "SELECT * FROM webid_categories WHERE parent_id = " . $rowid . " " . $catsort; $subres = mysql_query($subquery); $system->check_mysql($subres, $subquery, __LINE__, __FILE__); return $subres; } And heres the code that calls this function and passes the $row['cat_id'] value to it: // prepare categories list for templates/template // Prepare categories sorting if ($system->SETTINGS['catsorting'] == 'alpha') { $catsorting = ' ORDER BY cat_name ASC'; } else { $catsorting = ' ORDER BY sub_counter DESC'; } $query = "SELECT cat_id FROM " . $DBPrefix . "categories WHERE parent_id = -1"; $res = mysql_query($query); $system->check_mysql($res, $query, __LINE__, __FILE__); $query = "SELECT * FROM " . $DBPrefix . "categories WHERE parent_id = " . mysql_result($res, 0) . " " . $catsorting . " LIMIT " . $system->SETTINGS['catstoshow']; $res = mysql_query($query); $system->check_mysql($res, $query, __LINE__, __FILE__); while ($row = mysql_fetch_assoc($res)) { $subcats = getsub($row['cat_id'],$catsorting); while($subrow = mysql_fetch_assoc($subcats){ $template->assign_block_vars('sublist', array( 'SID' => $subrow['cat_id'], 'SNAME' => $category_names[$getrow['cat_id']] )); } $template->assign_block_vars('cat_list', array( 'CATAUCNUM' => ($row['sub_counter'] != 0) ? '(' . $row['sub_counter'] . ')' : '', 'ID' => $row['cat_id'], 'IMAGE' => (!empty($row['cat_image'])) ? '<img src="' . $row['cat_image'] . '" border=0>' : '', 'COLOUR' => (empty($row['cat_colour'])) ? '#FFFFFF' : $row['cat_colour'], 'NAME' => $category_names[$row['cat_id']] )); } then a .tpl file just references the {sublist.SID} and {sublist.SNAME} variables. BUT.... It ain't working. My page just goes blank. Any help would be massively appreciated. |
