How to show a specific row?
In HTML + PHP I would do something like this:
See the ID #5
And the show.php
<?php
$query = mysql_query("SELECT name FROM table WHERE id=$_GET[id]");
$row = mysql_fethc_assoc($query);
echo $row['name'];
?>
But how can I do this with only HTML + Sqlite?
I would have to solve the problem in this way.
<?php
$query = mysql_query("SELECT name FROM table WHERE id=$_GET[id]");
$row = mysql_fethc_assoc($query);
if($row['name']=="the name you want to find")
{
echo $row['name'];
}
?>

Im using mysql database. I want to make a link that link to a php page.
<?php
$connection = mysql_connect("localhost","root","");
mysql_select_db("scratchdisk",$connection);
$sql = "SELECT * FROM note";
$result = mysql_query($sql);
echo "<table>";
echo "<tr><td>#</td><td>Title</td><td>Action</td></tr>";
while($row=mysql_fetch_assoc($result)){
echo "<tr><td>".$row['#']."</td><td>".$row['Title']."</td><td><a href='view.php' id='view'>View</a></td></tr>"; }
echo "</table>";
?>
I want to display the next page base on my $row['#'] but the same view.php file.
You can use this code:
<?php
$connection = mysql_connect("localhost","root","");
mysql_select_db("scratchdisk",$connection);
$sql = "SELECT * FROM note";
$result = mysql_query($sql);
echo "<table>";
echo "<tr><td>#</td><td>Title</td><td>Action</td></tr>";
while($row=mysql_fetch_assoc($result)){
echo "<tr><td>".$row['#']."</td><td>".$row['Title']."</td><td><a href='view.php?id=" . $row['#'] . "' id='view'>View</a></td></tr>"; }
echo "</table>";
?>
In view.php
if(isset($_GET['id']) && !empty($_GET['id'])){
//Write logic here
$id = $_GET['id'];
}
So I am creating an inbox in PHP and It displays Mail Id and Subject.
If you click that division(containing mail id and subject), it opens up a new page, read. PHP where the body and attachments are displayed.
I am facing some problem in getting to know which division is being clicked and how to display the mail of that particular person.
My concerned code is:
<?php
$conn = connect(); //Connects to the database
$sql = "select senderId, subject, body, attachment from mail where receiverId = '".$_SESSION["Email"]."' ";
$result = $conn->query($sql);
while($row = $result->fetch_assoc()) {
echo "<div class='mail' onclick='location.href=`read.php`;'>";
echo $row["senderId"] . " - " . $row["subject"];
echo "</div>";
echo "<hr />";
}
$conn->close();
?>
I have an idea of storing the variables using SESSION as:
if (isset($_GET['div'])) {
$_SESSION["body"] = $row["body"];
$_SESSION["attachment"] = $row["attachment"];
}
But where do I place the latter part of the code and suggest me if I can make an modifications please.
You can echo out the id during the while loop iteration.
echo "<div class='mail' onclick='location.href=`read.php?id=". $row['id'] ."`;'>";
And inside the read.php file, you can then grab that value by using $_GET['id'].
How do I change the value of a SELECT tag in MATERIALIZE CSS. I'm trying show the selected item that was stored from the database. I tried adding .material_select() at the end of the select but it only retrieves the LAST one in the row. How do I show every try ? Here's what I've tried so far.
$(function() {
<?php
$q = $db->query("SELECT buildingID, buildingName,building_projectID, floorNumber FROM tblBuilding");
while($r = $q->fetch(PDO::FETCH_ASSOC)){
$buildingID = $r['buildingID'];
$buildingName = $r['buildingName'];
$building_projectID = $r['building_projectID'];
$floorNumber = $r['floorNumber'];
$t = $db->query("select projectName from tblProject where projectID = $building_projectID ");
while($u = $t->fetch(PDO::FETCH_ASSOC)){
$projectName = $u['projectName'];
?>
$("#editModal<?php echo $buildingID ?>").click(function(){
alert('<?php echo $projectName ?>');
$("#editBuildingName").val("<?php echo $r['buildingName'] ?>");
$("#editBuildingProject").val("<?php echo $projectName");
$("#editBuildingFloors").val("<?php echo $floorNumber ?>");
});
<?php }}?>
});
instead of:
$("#editBuildingProject").val("<?php echo $projectName");
use this:
$("#editBuildingProject").val("<?php echo $building_projectID ?>").material_select('update');
I am attempting to create a variable from a database array when an HTML link is clicked. The goal is to redirect the user to a form populated using one piece of array data. In other words, the database will be queried and form populated according to which link is clicked (whatever the values of $row[1], $row[2], and $row[3] are).
<?php
ini_set('display_errors',1); error_reporting(E_ALL);
$DATE = date('Y-m-d');
require_once 'IRCconfig.php';
$connection = new mysqli($db_hostname, $db_username, $db_password, $db_database);
if ($connection->connect_error) die($connection->connect_error);
$query = "SELECT * FROM CLIENT_CHECKIN1 WHERE DATE>='$DATE'";
$result = $connection->query($query);
if (!$result) die ("Database access failed: " . $connection->error);
$rows = $result->num_rows;
for ($j = 0 ; $j < $rows ; ++$j)
{
$result->data_seek($j);
$row = $result->fetch_array(MYSQLI_NUM);
echo <<<_END
<pre>
$row[1] $row[2] $row[3]
</pre>
_END;
}
?>
If anyone can provide me with some incite as to how I could accomplish this I'd appreciate it greatly.
Please read more about sessions here
Then, to answer your question:
First you need to start the session, as simple as session_start(); on the top of your script.
Second you need to instantiate session variables with the DB values like this: $_SESSION['var'] = $value;.
Third, in the html file or whatever, where the form relies, just check for it:
if(isset($_SESSION['var'])) {
echo '<input type="text" value="'.$_SESSION['var'].'" />';
} else {
echo '<input type="text" value="" />';
}
and use the value if it is set.
L.E:
So... first thing's first... session_start(); without it, there is no point of having session.
Second, you create it like $_SESSION['some_name'] = $row[1] so that var will keep the value from $row[1]. I am presuming that it's the value you need. Do NOT do do it like $_SESSION['$row1'] because first of all this is incorrect, you will NOT have the value of row1 there. You need an unique name so that you can call it where you have the form.
The above code will become something like this:
<?php
session_start();
ini_set('display_errors',1); error_reporting(E_ALL);
$DATE = date('Y-m-d');
require_once 'IRCconfig.php';
$connection = new mysqli($db_hostname, $db_username, $db_password, $db_database);
if ($connection->connect_error) die($connection->connect_error);
$query = "SELECT * FROM CLIENT_CHECKIN1 WHERE DATE>='$DATE'";
$result = $connection->query($query);
if (!$result) die ("Database access failed: " . $connection->error);
$rows = $result->num_rows;
for ($j = 0 ; $j < $rows ; ++$j)
{
$result->data_seek($j);
$row = $result->fetch_array(MYSQLI_NUM);
$_SESSION['first_row'] = $row[1];
$_SESSION['second_row'] = $row[2];
$_SESSION['third_row'] = $row[3];
echo <<<_END
<pre>
$row[1] $row[2] $row[3]
</pre>
_END;
}
?>
and, where you have the form and the <input type = "text" value = "" /> so where you need the value, just do it like this:
<input type = "text" value = "<?php echo (isset($_SESSION['first_row']) ? $_SESSION['first_row'] : ''); ?>" />
<input type = "text" value = "<?php echo (isset($_SESSION['second_row']) ? $_SESSION['second_row'] : ''); ?>" />
<input type = "text" value = "<?php echo (isset($_SESSION['third_row']) ? $_SESSION['third_row'] : ''); ?>" />
Hope this helps! :D
I am creating a form for inserting data which technologies are being used by which customers.
I get data of customer's ID and name and select a customer in an drop-down list, and i get data from technologies id and description and display description in a table + it creates a textbox (ID='box-". $row1['ID_T']."') for every technology entry in a DB.
So now i would like to check this dynamically created textboxes with jquery for value (if empty or filled with data) (getelementbyid) but i can not find a way to check theese DYN textboxes.
The ID_T and ID_C will be loaded into another table containing these two PK's and add string from textbox to value.
i would appreciate your help so much!
<HTML>
<HEAD>
<SCRIPT>
function update_tech(id,description)
{
var x = confirm('Do you want to edit technology '+description);
if (x == true)
{
document.getElementById('update_id').value = id;
//document.getElementById('description').value = description;
//document.form_update.submit();
}
}
</SCRIPT>
</HEAD>
<?php
include "connection.php";
$sql = "SELECT ID_C, Name FROM empresa";
$rs = mysql_query($sql, $conn);
$sql2 = "SELECT ID_T, description FROM technologies";
$rs2 = mysql_query($sql2, $conn);
while($row = mysql_fetch_array($rs2))
{
if (isset($_POST["box-".$row["ID_T"]]))
if ($_POST["box-".$row["ID_T"]] != "")
echo "INSERT ....".$_POST["box-".$row["ID_T"]]."<br>";
}
$rs2 = mysql_query($sql2, $conn);
mysql_close($conn);
?>
<BODY>
<SELECT NAME="customers" ONCHANGE="showCustomer(this.value)">
<?php
if (mysql_num_rows($rs))
{
while($row = mysql_fetch_array($rs))
{
?>
<option value='<?php echo $row['ID_C'] ?>'><?php echo $row['Name']?></option>
<?php
}
}
else {
echo "<option value=\"0\">No customers</option>";
}
?>
</SELECT>
<FORM METHOD="POST">
<?php
echo "<table border='0'>";
while($row1 = mysql_fetch_array($rs2))
{
echo "<tr>";
echo "<td><INPUT TYPE='text' name='box-". $row1['ID_T']."' ID='box-". $row1['ID_T']."'></td>";
echo "<td>" . $row1['description'] . "</td>";
echo "</tr>";
}
echo "</TABLE>";
?>
<INPUT TYPE="SUBMIT">
</FORM>
</BODY>
</HTML>
You can either maintain an array of input box ids or use the jquery partial selector to identify all the input boxes.
jQuery approach is something like:
$('input[id^="box-"]').each(function(e, i) { console.log(e); };
