I need to Query a database and then populate a textbox input with the result.
I'm trying
Date Called:
<td>
<?php
$selectedSPK=$_POST['SPKSelect'];
$assigned = $_POST['Sales_Exec'];
$date = $_POST['DateSelect'];
if ($selectedSPK)
{
$Call1query = "SELECT Call1 FROM Data WHERE SPKCustNo = '$selectedSPK' ";
$Call1result = mysql_query($Call1query);
while( $row = mysql_fetch_array($Call1result) ){
$Call1 = $row["$Call1Result"];
}
}
?>
<input type="text" name="Call1" id="Call1" value="<?php echo( htmlspecialchars( $Call1) ); ?>"/></td>
But getting nothing out, where am I going wrong, Text inputs seem tricky to populate!
Thankyou!
use instead
$Call1 = $row["Call1"];
Replace
$Call1 = $row["$Call1"];
with
$Call1 = $row["Call1"];
the problem is here change
$Call1 = $row["$Call1Result"];
to
$Call1 = $row['Call1']; //here column name comes not variable name
try like this
<td>
<?php
$selectedSPK=$_POST['SPKSelect'];
$assigned = $_POST['Sales_Exec'];
$date = $_POST['DateSelect'];
if ($selectedSPK)
{
$Call1query = "SELECT Call1 FROM Data WHERE SPKCustNo = '$selectedSPK' ";
$Call1result = mysql_query($Call1query);
while( $row = mysql_fetch_array($Call1result) ){
$Call1 = $row["Call1"];
}
}?>
<input type="text" name="Call1" id="Call1" value="<?php echo( htmlspecialchars( $Call1) ); ?>"/></td>

I have been following a lesson on how to make an admin page. I got all the information out of my database to a table on the page. I have an update button and when I change the information and press the button I receive this error: Warning: undefined array key "WebID" in ..\Update.php on line 3
From my search online everyone is trying to change the code so that if array key does not exist: return null. I tried that and the error does not appear no more, but the table does not change.
Any thoughts?
This is the code:
<?php
require_once("DB/DB.php");
$SearchQueryParameter = $_GET["WebID"];
if (isset($_POST["Update"])) {
$Ename = $_POST["Ename"];
$Eid = $_POST["Eid"];
$Erank = $_POST["Erank"];
$Eemail = $_POST["Eemail"];
$Edate = $_POST["Edate"];
$Epassword = $_POST["Epassword"];
$Specialisms = $_POST["Specialisms"];
global $ConnectingDB;
$sql ="UPDATE emp_data SET Ename='$Ename', Eid='$Eid', Erank='$Erank', Eemail='$Eemail', Edate='$Edate', Epassword='$Epassword',
Specialisms='$Specialisms' WHERE WebID='$SearchQueryParameter'";
$Execute = $ConnectingDB->query($sql);
if ($Execute) {
echo '<script>window.open("adminpage.php?WebID=Recored Updated","_self")</script>';
}
}
?>
<?php
<?php
global $ConnectingDB;
$sql = "SELECT * FROM emp_data WHERE WebID='$SearchQueryParameter'";
$stmt = $ConnectingDB->query($sql);
while ($DataRows = $stmt->fetch()) {
$WebID = $DataRows["WebID"];
$Ename = $DataRows["Ename"];
$Eid = $DataRows["Eid"];
$Erank = $DataRows["Erank"];
$Eemail = $DataRows["Eemail"];
$Edate = $DataRows["Edate"];
$Epassword = $DataRows["Epassword"];
$Specialisms = $DataRows["Specialisms"];
}
?>
Html file used to update:
<form id="UpdateForm" method="post" action="Update.php?WebID<?php echo $SearchQueryParameter; ?>">
<div class="form-group">
<button type="submit" name="Update" class="form-control-submit-button">Update</button>
</div>
you have to write the form action like this.. you missed the = sign
action="Update.php?WebID=<?php echo $SearchQueryParameter; ?>"
<form id="UpdateForm" method="post" action="Update.php?WebID=<?php echo $SearchQueryParameter; ?>">
You missed the = sign, in the url
I am trying to edit form data by displaying the previous saved data on the form and then update it. It shows the data on the form which is saved in database but when i enter the new data it does not get the id of the row. I echo the update query, it shows the changed values but it shows id equals to empty. Here is my code for edit record and update; Edit record is working but update isn't:
<?php
include('connection.php');
$id = '';
if( isset( $_GET['id'])) {
$id = $_GET['id'];
}
$udfname = mysql_real_escape_string($_POST["udfname"]);
$udlname = mysql_real_escape_string($_POST["udlname"]);
$udpwd = mysql_real_escape_string($_POST["udpwd"]);
$udeml = mysql_real_escape_string($_POST["udeml"]);
$udnum = mysql_real_escape_string($_POST["udnum"]);
$query="UPDATE form
SET fname = '$udfname', lname = '$udlname', pwd = '$udpwd', eml = '$udeml', num = '$udnum'
WHERE id='$id'";
$res= mysql_query($query);
if($res){
echo "<p> Record Updated<p>";
}else{
echo "Problem updating record. MY SQL Error: " . mysql_error();
}
?>
Form for editing record:
<?php
include('connection.php');
$id = (int)$_GET['id'];
$query = mysql_query("SELECT * FROM form WHERE id = '$id'") or die(mysql_error());
while($row = mysql_fetch_array($query)) {
echo "";
$fname = $row['fname'];
$lname = $row['lname'];
$pwd = $row['pwd'];
$eml = $row['eml'];
$num = $row['num'];
}
?>
<html>
<head>
<title>Edit</title>
<script>
'
'
Jquery code here
'
'
</script>
</head>
<body>
<form action="update.php" method="post">
<input type="hidden" name="ID" value="<?=$id;?>">
First Name: <input type="text" name="udfname" value="<?=$fname;?>"><br>
Last Name: <input type="text" name="udlname" value="<?=$lname?>"><br>

Contact Number: <input type="text" name="udnum" value="<?=$num?>"><br>
<input type="Submit">
</form>
</body>
</html>
At update time your form is submitted using POST request. So you need to get ID using POST method. So to get ID of hidden field change your code as below:
$id = '';
if( isset( $_POST['ID'])) {
$id = $_POST['ID'];
}
Please try below code
if( isset( $_POST['id']) && $_POST['id']!=null) {
$id = $_POST['id'];
}
Dear i think the problem with your method you are sending the data using post method and its very simple instead of this code
if( isset( $_GET['id'])) {
$id = $_GET['id'];
}
write
if( isset( $_POST['id'])) {
$id = $_POST['id'];
}
and one more thing that is you are using the mysql deprecated function for database kindly use the pdo for this or new mysqli functions.
I have a search function on my website with 4 checkboxes. These are then pasted to the next page where I want to find all products which match the criteria of the check boxes.
As I have 4 check boxes I want to use 4 'ands' but I believe 3 is the max (?)
How can I get around this so it searches to see if all products are matched?
HTML Form
<div id = "search">
<form name = search action = "search.php" method = "POST">
<p class = "big"> Refine Menu </p>
<hr>
<input type = "text" name = "search" placeholder = "Search for an item" size = "12">
<input type = "submit" value = "Go">
<br><br>
<input type = "checkbox" name = "vegetarian"> Vegetarian
<br><input type = "checkbox" name = "vegan"> Vegan
<br><input type = "checkbox" name = "coeliac"> Coeliac
<br><input type = "checkbox" name = "nutFree"> Nut free
</form>
</div>
PHP
<?php
session_start();
include "connection.php";
if(!isset($_SESSION["username"])){
header("Location: login.php");
}
if(isset($_POST["search"])){
$search = $_POST["search"];
}
if(isset($_POST["vegetarian"])){
$vegetarian = 1;
}
else{
$vegetarian = NULL;
}
if(isset($_POST["vegan"])){
$vegan = 1;
}
else{
$vegan = NULL;
}
if(isset($_POST["coeliac"])){
$coeliac = 1;
}
else{
$coeliac = NULL;
}
if(isset($_POST["nutFree"])){
$nutFree = 1;
}
else{
$nutFree = NULL;
}
$sql = "SELECT * FROM products WHERE vegan = '$vegan' and nutFree = '$nutFree' and vegetarian = '$vegetarian' and coeliac = '$coeliac'";
$result = mysqli_query($con, $sql);
while($row = mysqli_fetch_assoc($result)){
echo $row ["name"];
}
I've tried a number of different thing but I don't know the correct syntax for the sql.
NOTE: In my database whether it meets the requierment on it is saved as either a 1 or 0 that is why I changed it from 'on' or 'off'
Rather than a large, unmaintainable chain of if statements, you might consider something similar to the following, which will dynamically build up your query depending on which of your required fields have been checked in your form:
<?php
$search_fields = array( 'vegetarian', 'vegan', 'nutFree', 'coeliac', ...);
$ands = array( '1' => '1');
foreach($search_fields as $req)
{
if(isset($_POST[$req]) && $_POST[$req] != '')
{
$ands[$req] = "$req = '1'";
}
}
$and_part = implode(" AND ", $ands);
$query = "select .... from ... WHERE $and_part ... ";
?>
I managed to solve my problem. I was mistaken when I posted the question because the reason I thought my sql statement wasn't working was because there were too many ands and I didn't see that rather my sql didn't do what I thought it should.
Here is what I changed it to or it has set values or the check boxes ticked but always the ones which aren't to be either or.
Thanks for everyone's help!
<?php
session_start();
include "connection.php";
if(!isset($_SESSION["username"])){
header("Location: login.php");
}
if(isset($_POST["search"])){
$search = $_POST["search"];
}
if(isset($_POST["vegetarian"])){
$vegetarian = 1;
}
else{
$vegetarian = " ";
}
if(isset($_POST["vegan"])){
$vegan = 1;
}
else{
$vegan = " " ;
}
if(isset($_POST["coeliac"])){
$coeliac = 1;
}
else{
$coeliac = " " ;
}
if(isset($_POST["nutFree"])){
$nutFree = 1;
}
else{
$nutFree = " ";
}
$sql = "SELECT * FROM products WHERE (vegan = '$vegan' or vegan = 1 xor 0) and (nutFree = '$nutFree' or nutFree = 1 xor 0) and (vegetarian = '$vegetarian' or vegetarian = 1 xor 0) and (coeliac = '$coeliac' or coeliac = 1 xor 0)";
$result = mysqli_query($con, $sql);
while($row = mysqli_fetch_assoc($result)){
echo $row ["name"];
}
PHP's NULL have no significance when converted to a string (the SQL query), they will evaluate to empty and your query will look like nutFree = '' and vegetarian = '' and coeliac = ''.
If those fields are 0 in the database, you must set the variables to 0 then.
On a second case, if they are NULL in the database, you must change both your query and the way you define NULL here.
First, those string wrappers should go away. You don't need them for numbers anyway, those are supposed to wrap strings only:
$sql = "SELECT * FROM products WHERE vegan = $vegan and nutFree = $nutFree and vegetarian = $vegetarian and coeliac = $coeliac";
And then instead of setting the variables to NULL, you will set them to the string "NULL".
$nutFree = "NULL";
This will make NULL show on the SQL query as its expected to.
// query
$sql = "INSERT INTO tool (title,details) VALUES (:title,:details) ";
$q = $conn->prepare($sql);
$q->execute(array(':details'=>$details,
':title'=>$title));
Been having trouble with this all day, I've finally got it down to this. If I use the above code, it will just add a new post to the database. This is supposed to be used for editing a post, so obviously I need to edit existing information:
// query
$post = htmlspecialchars($_GET['story']);
$sql = "UPDATE tool SET (title,details) VALUES (:title,:details) WHERE id = $post";
$q = $conn->prepare($sql);
$q->execute(array(':details'=>$details,
':title'=>$title));
'id' is a column in the database. I need it to update the title, and details, for that specific post. I'm just not sure what syntax I'm supposed to be using here.
Thanks for any answers!
===== Second question:
Now I'm back to my old error. Whenever I edit a post, it will lose the title and details, only once. The first time I edit the post, I lose all information, but the rest of the times it will work just fine. Any idea why? Heres the code:
Form from the edit page(may or may not be important, I don't know):
$name = $_SESSION['Username'];
if (in_array($name, $allowedposters)) {
$results = mysql_query("SELECT * FROM tool WHERE id = $post");
while($row = mysql_fetch_array($results)){
$title= $row['title'];
$details= $row['details'];
$date= $row['date'];
$author= $row['author'];
$id= $row['id'];
echo "<a href=story.php?id=";
echo $post;
echo ">Cancel edit</a> <br><br><b>";
echo $title;
echo "</b> <br><br>";
echo '
<form action="edit-new.php?story=';
echo $id;
echo '" method="post" enctype="multipart/form-data">
<textarea rows="1" cols="60" name="title" wrap="physical" maxlength="100">';
echo $title;
echo '</textarea><br>';
?>
<textarea rows="30" cols="60" name="details" wrap="physical" maxlength="10000">
<?php
echo $details;
echo '</textarea><br>';
echo '<label for="file">Upload featured image:</label><br>
<input type="file" name="file" id="file" />';
echo'<br><input type="submit" />';
}
} else {
echo "Not enough permissions.";
}
?>
Here is the SQL, inserting into DB:
<?php
$post = htmlspecialchars($_GET['story']);
$title = mysql_real_escape_string($_POST['title']);
$details = mysql_real_escape_string($_POST['details']);
echo "B<br>";
echo $_POST['title'];
echo '<br>';
echo $_POST['details'];
echo $post;
echo "<br><br>";
// configuration
$dbtype = "mysql";
$dbhost = "localhost";
$dbname = "zzzz";
$dbuser = "zzzzz";
$dbpass = "zzzzzz";
// database connection
$conn = new PDO("mysql:host=$dbhost;dbname=$dbname",$dbuser,$dbpass);
// new data
// query
$sql = "UPDATE tool SET title=:title, details=:details WHERE id = :postid";
$q = $conn->prepare($sql);
$q->execute(array(
':details'=>$details,
':title'=>$title,
':postid' => $post
));
?>
Fix your sql UPDATE syntax
$sql = "UPDATE tool SET title=:title, details=:details WHERE id = :postid";
$q = $conn->prepare($sql);
$q->execute(array(
':details'=>$details,
':title'=>$title,
':postid' => $post
));
what I'm trying to do is run a select statement for each answer to select the answer in the database where the questionID = $i and the userID = $userID so I have the query like this set up so far but not sure what I'm missing or am I right and not missing anything? Also no matter what i do both fields have values but I'm still getting the error message that I need to fill out both form fields.
<?php
$i = 1;
while ($row = mysqli_fetch_array($result, MYSQLI_ASSOC)) {
?>
<dl>
<dt style="width: 190px;"><label for="answer[<?php echo $row['id']; ?>]"><?php echo $row['question'] ?></label></dt>
<dd><input type="text" name="answer<?php echo $i ?>[<?php echo $row['id']; ?>]" size="54" /></dd>
</dl>
<?php
++$i;
}
?>
if (empty($_POST['answer1'][$i]) || trim($_POST['answer1'][$i])=="") {$errors = "yes";}
if (empty($_POST['answer2'][$i]) || trim($_POST['answer2'][$i])=="") {$errors = "yes";}
// Error checking, make sure all form fields have input
if ($errors == "yes") {
// Not all fields were entered error
$message = "You must enter values to all of the form fields!";
$output = array('errorsExist' => true, 'message' => $message);
} else {
$userID = mysqli_real_escape_string($dbc,$_POST['userID']);
$answer1 = mysqli_real_escape_string($dbc,$_POST['answer1'][$i]);
$answer2 = mysqli_real_escape_string($dbc,$_POST['answer2'][$i]);
$query = "SELECT * FROM manager_users_secretAnswers WHERE questionID = '".$questionID."' AND userID = '".$userID."'";
$result = mysqli_query($dbc,$query);
echo $query;
You can have a problem with php type autoquessing. Let suppose thatyou have questions with ids: 3,5,7,8 then you are using:
empty($_POST['answer1'][$i])
$_POST['answer1'][3] so you are fetching third element of array.
So I suggest to use not array notation, but:
For input name: answer|${id} or answer_${id} instead of answer[$id]
