PHP - Put Variable Into Url Via Button Href
ok so I just want to get the username into the url after the button is clicked
Code: [Select] <?php $val = 123; ?> <a href="index.php>Button</a> How do I get the href to be Code: [Select] index.php?user=123 all help greatly appreciated. thanks Similar TutorialsHello I have a website that I am trying to upgrade so that all the data can be placed into a MySql database. I know what I need but I do not know if it is possible with PHP and MySql. I need to insert into a Href link a variable so that when the link is clicked it would initiate a MySql search for data. The variable would contain the Key id of the person whose name was clicked. This is very difficult to explain so a visit to the static website may help understand what I am trying to achieve, www.westonheritage.co.uk If you go to the second page by clicking the key then click on any of the surnames listed. I have the database setup on localhost and can get out the data I require. Kind regards I'm new to php and was wondering how I would be able to do the following: -I have a search page that allows someone to search for a particular user in the database -In the results, I want to have a <a href> link to another page which will run a sql query based on which user's link was clicked and list their posts. So right now I have been trying this code to build that href link: Code: [Select] echo '<td><a href="viewuser.php?username='.urlencode($row['username']).'>View user</a></td>'; However on the following page it is unable to retrieve the 'username' field. How can I set a variable when <a href="#">Link</a> is clicked? for example to set $variableX as integer of 1? This topic has been moved to Ajax Help. http://www.phpfreaks.com/forums/index.php?topic=308673.0 Hello Everyone, I'm using PHP with MySQL. One of the fields in the database is website. The code I'm using is as follows: variable: $web=mysql_result($result,$i,"web"); html/php code: <td><font face="Arial, Helvetica, sans-serif"><a href="<? echo "$web"; ?>">Website</a></font></td> What it should do is have the clickable word Website with the correct url from the database. Instead it's repeating the website the page is on. For example it's doing this: http://mywebsite/www.enteredwebsite.com Any help is appreciated. This works: Code: [Select] form action="http://localhost/mysite/css/screen.css" method="post"> This does not work: Code: [Select] <?php $link_1 = "http://localhost/mysite/css/screen.css" ; $link_2 = '"' . "http://localhost/mysite/css/screen.css" .'"' ; ?> <form action=<?php echo $link_1;?> method="post"> <form action=<?php echo $link_2;?> method="post"> Why do neither of the PHP variables work? Thanks! I have a php page that is trying to pass a variable like this: echo "<tr><td bgcolor='white'>" . $company_id . "</td><td bgcolor='white'><a href='companyusers.php?name=" . $company_name . "'>" . $company_name . "</a></td><td bgcolor='white'>" . $company_email . "</td><td bgcolor='white'>" . $company_status . "</td></tr>"; Then when some one clicks on that link they variable with it's value should go with the url and I'm trying to assign a variable like this: $company_name = $_POST['name']; It is not working!!! I get that "Notice: Undefined index: name in 'directory of page' on line 100" Can someone help please? I am trying to allow the user to update a variable he chooses by radio buttons, which they will then input text into a box, and submit, to change some attributes. I really need some help here. It works just fine until I add the second layer of variables on top of it, and I can't find the answer to this question anywhere. <?PHP require('connect.php'); ?> <form action ='' method='post'> <select name="id"> <?php $extract = mysql_query("SELECT * FROM cars"); while($row=mysql_fetch_assoc($extract)){ $id = $row['id']; $make= $row['make']; $model= $row['model']; $year= $row['year']; $color= $row['color']; echo "<option value=$id>$color $year $make $model</option> ";}?> </select> Which attribute would you like to change?<br /> <input type="radio" name="getchanged" value="make"/>Make<br /> <input type="radio" name="getchanged" value="model"/>Model<br /> <input type="radio" name="getchanged" value="year" />Year<br /> <input type="radio" name="getchanged" value="color" />Color<br /><br /> <br /><input type='text' value='' name='tochange'> <input type='submit' value='Change' name='submit'> </form> //This is where I need help... <?PHP if(isset($_POST['submit'])&&($_POST['tochange'])){ mysql_query(" UPDATE cars SET '$_POST[getchanged]'='$_POST[tochange]' where id = '$_POST[id]' ");}?> Hi guys; I've managed to find my way into something of a maze. <td> <a href="'Details/21/index.php'"?id= . $id .'>" . $row['id'] . "</a> </td> I'm looking at this line in the code. I realise it's currently in the wrong syntax but I'm just trying multiple different variations. At the moment I'm actually just trying to make it go to a static link but my real goal is to - get it to pick up the id number, of the id row I click, and concatenate that with the rest of my address string. Then use that as the href. Something like this: - "'Details/' + $id + '/index.php'" It's really confusing me though inside this loop and for some reason the id number is being picked up as an int, by the looks of things. It's getting above my level of understanding. Any chance one of you masters would through a n00b a lifeline?

Edited February 8, 2020 by JonnyDriller Hey all, I'm almost too embarrased to post this as I'm sure it is very simple - but for the life of me I can't get this to work. I am a complete newbie to PHP so please bear with me.. What I'm trying to do is to write a program that will go on to calculate a user's Body Mass Index (BMI) based on user inputted data of height and weight. However, I want to be able to accept heights and weights in a number of different units for maximum ease of use. I am trying to write some PHP code that will handle this , the main goal is to convert everything into 'cm' and 'kg' before going on and doing the simple BMI calculation later on. However I am stuck at this point: I have a text field for users to input their weight into. This is immediately followed by two radio buttons for the user to select which units they are inputting their weight in (kilograms or pounds). A third option to input their weight is given after this for those wishing to input their weight in 'stones and pounds'. My problem is as follows: I can't get my code to recognise which radio button (either 'kg' or 'lbs') has been pressed. What should happen is that my code can tell something has been inputted in the text box AND which of the radio buttons has been selected. From this it does one of the two; for the kilogram option it leaves the value as it is, but if the weight has been inputted in pounds (and the 'lbs' radio button selected) then I want the code to convert this into kilos by multiplying by 0.4535. Here is what I have so far (sorry its a bit messy - like i say I am a newbie): <?php //convert.php $ft = $cm = $inches = $weight = $stones =$pounds = $kilos = $units = ""; if(isset($_POST['cm'])) $cm = sanitizeString($_POST['cm']); if(isset($_POST['ft'])) $ft = sanitizeString($_POST['ft']); if(isset($_POST['inches'])) $inches = sanitizeString($_POST['inches']); if(isset($_POST['weight'])) $weight = sanitizeString($_POST['weight']); if(isset($_POST['stones'])) $stones = sanitizeString($_POST['stones']); if(isset($_POST['pounds'])) $pounds = sanitizeString($_POST['pounds']); if(isset($_POST['kilos'])) $kilos = sanitizeString($_POST['kilos']); if(isset($_POST['units'])) $units = sanitizeString($_POST['units']); if ($ft != '') { $height = intval(($ft * 30.48) + ($inches * 2.54)); $out = "you are $height cm tall"; } elseif($cm != '') { $height = intval($cm); $out = "you are $height cm tall"; } else $out = ""; if ($stones != '') { $kilos = intval((($stones * 14) + $pounds) * 0.45359237); $out2 = "you weigh $kilos Kg"; } elseif($weight != '' AND $units = "kg") { $kilos = $weight; $out2 = "you weigh $kilos Kg"; } elseif($weight != '' AND $units = "lbs") { $kilos = ($weight * 0.45359237); $out2 = "you weigh $kilos Kg"; } else $out2 = ""; echo <<<_END <html><head><title>Height & Weight Converter</title> </head><body><pre> Please enter your details below <b>$out$out2</b> <form method="post" action="convert.php"> Height: <input type="text" name="cm" size="3"> cm OR <input type="text" name="ft" size="1">ft <input type="text" name="inches" size="2">inches Weight: <input type="text" name="weight" size="4" /> Kg<input type="radio" name="units" value="kg" /> lbs<input type="radio" name="units" value="lbs" /> OR <input type="text" name="stones" size="2">stone <input type="text" name="pounds" size="2">pounds <input type="submit" value="Submit" /> </form></pre></body></html> _END; function sanitizeString($var) { $var = stripslashes($var); $var = htmlentities($var); $var = strip_tags($var); return $var; } ?> I know this is 'old stuff', but I am new to this and very frustrated- I am trying to pass a variable to a new url via an html onclick event, and failing. I have found several posts about it but the code posted in those posts does not work when I try it. I have struggled mightly with this. Here is my code: first an echo of two versions of the onclick statement, and two versions of the actual button code. The echos from the two versions appear identical, but the first button with no variable works while the second using a variable results in no action. Can anyone point me in the direction of a solution? I suspect there is some simple principal I am missing relating to parsing strings. <?php echo "window.location.href='ManageTitles.php?dog=2'"; echo "\n" ; echo "window.location.href='ManageTitles.php?dog={$row_rsDogsowned['idDogInfo']}'"; ?> <form methd="POST" Name="form3" action="<?php echo $editFormAction; ?>"> <input type="button" value="works" onclick="window.location.href='ManageTitles.php?dog=2'" /> <input type=button onclick="window.location.href='ManageTitles.php?dog={$row_rsDogsowned['idDogInfo']}'" value="fails" /> </form Hello World, I need some tips on how to make a button that does something like the code below. .......echo '<tr><td align="left"><a href="add_cart.php?pid=' . $row1['item_id'] . '">Add to Cart</a></td>........ I've been messing with html form and button type with no success. This code does the job but I prefer a button. Thanks I am new at php. I am trying to loop a number in each click of a button. See attached picture for reference. 1 should iterate after the click of the button and will stop to iterate when it gets to 5.
Here is my code:
<!DOCTYPE html>
<html>
<body>
<div>Question <?php $num = 5; $n = 1; $n <= $num; echo $n; ?> of <?php echo $num;?></div>
<form method="post"> <button id="button" class="button" value="add" name="add">Click</button> </form>
</body>
</html>
If I try to loop it this way,
<!DOCTYPE html>
<html>
<body>
<div>Question <?php $num = 5; for($i = 1; $i <= $num; $i++){ echo $i; } ?> of <?php echo $num;?></div>
<form method="post"> <button id="button" class="button" value="add" name="add">Click</button> </form>
</body>
</html>
the result is Question 12345 of 5.

The code below is what I have this far. In some way when I click the send button it always gives the last username in the table in the $_Post variable. Can anyone help me please. Thnx Ryflex <?php require_once('auth.php'); require_once('config.php'); $global_dbh = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD) or die("Could not connect to database"); mysql_select_db(DB_DATABASE, $global_dbh) or die("Could not select database"); $user_query = "SELECT * FROM members"; $user_result = mysql_query($user_query); ?> <form ID="gotoresource" NAME="gotoresource" METHOD="POST" ACTION="resource_compose.php"> <table width="500" border="1" align="center" cellpadding="2" cellspacing="0"> <tr> <td><b>User</b></td> <td><b>Resource</b></td> </tr> <?php while($row = mysql_fetch_assoc($user_result)) { echo "<tr>"; echo "<td>"; echo $row['login']; $user = $row['login']; ?> <input name="User" type="hidden" maxlength="15" id="user" value="<?php echo $user; ?>"/> </td> <td> <input type="submit" name="Submit" value="Send" /> </td> <?php echo "</tr>"; } ?> <html> <head> <title>Userlist</title> <link href="loginmodule.css" rel="stylesheet" type="text/css" /> </head> <body> </body> </html> what would be the $_POST variable name for a radio button option? This topic has been moved to JavaScript Help. http://www.phpfreaks.com/forums/index.php?topic=350095.0 I am trying to create a page for customers to enter their details. I am using a html form.
When the submit button is pressed the form posts the inputs to the same page, which then checks if the inputs are empty. If they are not then each post variable is allocated a session variable so this info can be accessed late on in the system.
If some of the inputs are empty then the value of the input forms become equal to the session variables that they were just allocated to so that the customer doesn’t have to retype their information.
This is where the problem occurs. When I load the page each input box has a slash inside it and when the submit button is pressed a mother slash is added.
My code is below:
<?php
session_start();
if(isset($_POST['NextPage'])){
if (!empty($_POST['CName'])){
$_SESSION["CName"] = $_POST['CName'];
if (!empty($_POST['CStreet'])){
$_SESSION["CStreet"] = $_POST['CStreet'];
if (!empty($_POST['CTown'])){
$_SESSION["CTown"] = $_POST['CTown'];
if ($_POST['Counties'] != "-"){
$_SESSION["CCounty"] = $_POST['Counties'];
if (!empty($_POST['CPostcode'])){
$_SESSION["CPostcode"] = $_POST['CPostcode'];
if (!empty($_POST['CEmail'])){
$_SESSION["CEmail"] = $_POST['CEmail'];
if (!empty($_POST['CNumb'])){
$_SESSION["CNumb"] = $_POST['CNumb'];
$NotEmpty = true;

Hi all, I have written a piece of code querying the database to display the last ten posts from different users on a forum/blog. This is displaying the titles of the posts but I am unsure how to create a link (complete novice) to read the content of those posts. I get the syntax etc but can't really get my head around the target, if you catch my drift. I have created a new php file called recentposts but am unsure of how to take it from there. The code for both is below. The first piece of code works fine but when I click read more I am getting an undefined variable message on line 11 (I'm guessing there should be a link between the two pieces of code) and I am getting mysqli_fetch_array() expects parameter 1 to be mysqli_result on line 12. Any thoughts/hints/suggestions welcome. Thanks in advance. Code: [Select] <?php $connection = @mysqli_connect('localhost','root','','BLOG_PROJECT') //Make a connection to the database or die(mysqli_connect_error("Could not connect to the server")); //If it doesn't connect give the error message $latestposts= mysqli_query($connection,"SELECT author_id, title FROM blogposts ORDER BY timeofpost DESC LIMIT 9");//Query the database while($displayposts=@mysqli_fetch_array($latestposts)){ //go and get the information echo "{$displayposts['title']}</br>"; echo "<a href='recentposts.php'>Read more</a></br>"; } ?> And the recentposts.php is Code: [Select] <?php $connection = @mysqli_connect('localhost','root','','BLOG_PROJECT') or die(mysqli_connect_error("Could not connect to the server")); $detail= mysqli_query($connection,"SELECT * FROM blogposts WHERE 'title', 'content', 'timeofpost' = $content"); while($singlepage = mysqli_fetch_array($connection,$detail)){ extract($singlepage); echo "<h2>{$singlepage['title']}</h2></br>"; echo "{$singlepage['content']}</br>"; echo "{$singlepage['timeofpost']}"; } ?> Friends I am new to php and i have to submit my coursework in php by 3rd dec, I stuck at one place where i have to upload multiple photo and one can see all the photo he has uploaded and can edit or delete that photo so i have done uploading now i am showing those pics in table by running loop and generating tr and td but now i have two buttons with each row edit and delete now when i clicked on one delete or edit that pic should be delete or give text box to edit description of pic, Please help me how to do that....... |
