I am having an issue to pass a textarea to another page when contains more than one line.
I have 3 pages:
1.-_testInsertText.php = INSERT a new text in Database
2.-_testShowText.php = SELECT the texts from Database and redirect to Modify Page
3.-_testTextModify.php = UPDATE the text passed by _testShowText.php
My structure from my table from Database:
CREATE TABLE `tblTest`
(
`clmSerie` int (11) NOT NULL
,`clmTextArea` text NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
If I insert a text with two lines through _testInsertText.php I am able to display correctly through _testShowText.php
My problem is in redirecting (through href) those records with more than one line to _testTextModify.php page (For 1 line is working fine). It is not redirecting.
Could you please help me?
My code can be found below:

Thanks to comment by Sloan Thrasher, I modified _testTextModify.php and _testShowText.php
And now I am passing content to a hidden TextArea instead of a href to the modify page and it is working fine now when it comes with more than one line.
Thank you everyone :)
The new code below:
_testTextModify.php
<?php
if(isset($_POST['fromTestShowText']))
{
$txtEvolucionOld = $_POST['descripcion'];
$idSerie = $_POST['serie'];

if(isset($_POST['Modify']) && isset($_POST["txtEvolucionOld"]))

I'm having the problem to pull out data from my database through a search field. I'm trying to protect my searchfield against Sql injection at the same time. Adding data to my database is working fine, and I think i did fine safetywise. Yet, pulling the data out seems to be harder.
All i'm trying to achieve is getting all the data from the person. I'm looking for "Bart" in my search field, so show me all the data from all the Barts in my database.

$stmte->execute();
echo $zoeknaam;
}
?>
Am i wrong to think that i'm not fetching something? And that is the reason i'm not getting anything?
EDIT ------>
Edited version as suggested below: Errors are gone but no results show up:
<?php
require_once 'login.php';
$db_con= new mysqli($db_host, $db_username, $db_password, $db_database);
$db_con->set_charset("utf8");
if($db_con->connect_error) die ("(" . $db_con->connect_error . " Error during connection");
if(isset($_POST['zoeken'])){
$zoeknaam = $_POST['Zoek']; // declare the input here
$stmte = $db_con->prepare("SELECT * FROM customers WHERE Voornaam = ?");
$stmte->bind_param("s", $zoeknaam); // then use inside here
$stmte->execute();
$rows = $stmte->num_rows;
for($i=0; $i < $rows; $i++){
$row=mysqli_fetch_array($stmte, MYSQLI_ASSOC);
echo $row['Voornaam'] . '<br/>';
}
/*if($stmte->num_rows > 0) {
$results = $stmte->get_result();
while($row = $results->fetch_assoc()) {
echo $row['Achternaam'] . '<br/>';
// and other columns
}*/
}
?>
You should fetch the results properly by using ->get_result(). After that, you would be able to use ->fetch_assoc(). Example:
$zoeknaam = $_POST['Voornaam']; // declare the input here
$stmte = $db_con->prepare("SELECT * FROM customers WHERE Voornaam = ?");
$stmte->bind_param("s", $zoeknaam); // then use inside here
$stmte->execute();
if($stmte->num_rows > 0) {
$results = $stmte->get_result();
while($row = $results->fetch_assoc()) {
echo $row['Voornaam'] . '<br/>';
echo $row['Achternaam'] . '<br/>';
// and other columns
}
}
If unfortunately, you do not have mysqlnd in your environment (if ->get_result() turns out the be Call to undefined method). Here's another way:
$zoeknaam = $_POST['Voornaam'];
$stmte = $db_con->prepare("SELECT * FROM customers WHERE Voornaam = ?");
$stmte->bind_param("s", $zoeknaam);
$stmte->execute();
// get all columns
$meta = $stmte->result_metadata();
while ($field = $meta->fetch_field()) {
$params[] = &$row[$field->name];
}
call_user_func_array(array($stmte, 'bind_result'), $params);
while ($stmte->fetch()) {
echo $row['Voornaam'] . '<br/>';
echo $row['Achternaam'] . '<br/>';
}
So I'm currently working with a form where the admin can select multiple users from the database via a tickbox system, then change the welcome message or general message to a client when they log in:

So this is the form, and it works fine, it calls all users from the database and displays them in tickbox fasion.
I can only assume my issue is in the exec script:
<?php
echo( "<pre>" );
print_r( $_POST );
echo( "</pre>" );
include ("config.php");
$tbl_name="members";
//Connect to mysql server
$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
if(!$link) {
die('Failed to connect to server: ' . mysql_error());
}
//Select database
$db = mysql_select_db(DB_DATABASE);
if(!$db) {
die("Unable to select database");
}
//This gets all the other information from the form
$update = $_POST['otherdeets'];
$id = $_POST['userid'];
// Cycle through each member and check that it needs to be added to the db
$useruploadids = mysql_query( "SELECT member_id FROM members" );
while ($row = mysql_fetch_assoc($useruploadids))
{
// Check that the member was sent from the last form
if( isset( $_POST['userid_'.$row['member_id']] ) && $_POST['userid_'.$row['member_id']] == "y" )
{
// update data in mysql database
$sql="UPDATE $tbl_name SET otherdeets='$update' WHERE id='$id'";
$result=mysql_query($sql);
}
}
if($result){
echo "Successful";
echo "<BR>";
echo "<a href='admin-welcome.php'>Admin Home</a>";
}
else {
echo "ERROR";
}
?>
When I run the script it simply says:
Array
(
[userid_1] => y
[otherdeets] => Blah Blah
[Submit] => Update
)
ERROR
Any idea what is wrong? Knowing my luck it would probabaly be a spelling mistake
Thank you
Hey your query is wrong there should be where condition with appropriate column name i.e. "member_id"
And one more thing
you are fetching the $id = $_POST['userid']; which is an error as there is no value exist with that key
rather you do in the if condition before doing the update query, i.e.
$id = $POST['userid'.$row['member_id']];
