I have the following,
when the below code process', it gives me a list of ID's etc and Description and Subject. Now since there is a form i put within the loop, when i go to click on "View" button which then display only that specific "Ticket" the issue is, it always displays the same ticket. the last one in the array. why?
foreach ($results['results'] as $item) {
echo 'Ticket ID # '. $item['id'] . ' Subject: '. $item['subject'] .'<br/>';
echo 'Description : '. $item['description'] .'<br/>';
echo "<form action=\"view.php\" method=\"post\">";
echo '<input type="text" name="TicketID" value="'. $item['id'] .'"/>';
echo "<input type=\"submit\" name=\"View\" value=\"View\" />";
echo "<br>";
echo "<br>";
}
You do not close the <form> tag - simply add between the last <input> element and the <br> elements an echo '</form>'; line.

I'm generating a html table. Each row starts with a Edit-Button.
Site A:
echo "<table border='1' align='center'>";
echo "<tr>"
. "<th style='font-weight:bold'></th>"
. "<th>".$nr.":</th>"
. "<th>Anschrift</th><th>Nachname</th>"
. "<th>Vorname</th>"
. " <th>PLZ</th>"
. "<th>Ort</th>"
. "</tr>";
echo "<form action='lxKundenEdit.php' method='POST'>";
$i=0;
foreach($arr as $key =>$value)
{
echo "<tr><td><input type='submit' name='btn'.$i.'\'' value='Bearbeiten'/></td>";
foreach($value as $subkey=>$subValue)
{
echo "<td>".$subValue."</td>";
}
echo "</tr>";
$i++;
}
echo "</form>";
echo "</table>";
Then I want to know which button has been pushed. When vardump the POST-Array it seems nothing really works. Any hints about this? regards, Ismir
Site B:
var_dump($_POST['btn0']); //f.e.
Simply pass the sender ID in a hidden input
<input type="hidden" name="sender" value="<?= $senderID; ?>">
On Site B you can then get the value from the $_POST variable:
echo $_POST['sender'];
Edit
I see I misread your question. What you can do is pass your subkey on the submit button as follows:
<input type="submit" name="submit[<?= $subkey; ?>]" value="send" />
You should give each button a unique value. When the form is posted you can then check for that value for that button.
echo '<input type="submit" name="btn'.$i.'" value="'.$i.'" />';
Edit:
As Peter pointed out in the comments, if you want to change the text of your button, you can use the button element:
<?php
echo '<form method="post">';
echo '<button type="submit" value="button 1 was used" name="button">Send</button>';
echo '<button type="submit" value="button 2 was used" name="button">Send</button>';
echo '</form>';
var_dump( $_POST[ 'button' ] );
All you need to do is:
Make array of all your submit buttons with ids as keys.
echo '<tr><td><input type="submit" name="btn[<?php echo $i;?>]" value="Bearbeiten"/></td>';
And then in PHP, get posted submit buttons like:
if (! empty($_POST['btn']) {
foreach ($_POST['btn'] as $btnId => $btnVal) {
// $btnId is Id of the button that is $i
// $btnId means button is pressed.
// $btnVal is value of the button
}
}
Just include a hidden input inside your form, eg
<input type='hidden' name='submit'/>
So you can use it to check, if the form has been sent (if(isset($_POST['submit'])) etc). Then check any other $_POST fields looking for any ['btn...'], eg
foreach($_POST as $key => $value){ // check all the $_POST fields
if(substr($key,0,3) == 'btn'){ // if its name begins with 'btn'...
$button_id = substr($key,3,NULL); // then that's some button. Get its ID
}
}
Think this should work
I have a form with 2 selects, when you send the first, the second select charges the values that are called on my oracle bd with a query, then when i send the second select, it generates a table with checkboxes:
if(isset($idTActi)){
$stallTableTarifas=oci_parse($conn, "SELECT TARIFAS.ID, TARIFAS.ID_TIPO_ACTIVIDAD, TARIFAS.TIPO, TIPO_ACTIVIDAD.TEMPS_KM, TARIFAS.PRECIO
FROM TARIFAS, TIPO_ACTIVIDAD
WHERE TARIFAS.ID_TIPO_ACTIVIDAD = TIPO_ACTIVIDAD.ID
AND TARIFAS.ID_TIPO_ACTIVIDAD = $idTActi");
oci_execute($stallTableTarifas);
echo "<div class='divPrecios'>";
echo "<table>";
echo "<tr class='tabPreciosTitles'>";
echo "<td>Tipus Tarifa</td>
<td>Temps/Km</td>
<td>Preu</td>
<td><input type='submit' class='carrito' value=''></td>";
echo "</tr>";
while (($row=oci_fetch_array($stallTableTarifas,OCI_BOTH))!=false){
echo "<tr>";
echo "<td>".$row['TIPO']."</td>";
echo "<td>".$row['TEMPS_KM']."</td>";
echo "<td>".$row['PRECIO']."</td>";
echo "<td><input type='checkbox' name='checkbox[]' value='".$row['ID']."'/></td>";
echo "</tr>";
}
echo "</table>";
echo "</div>";
}
echo "</form>";
The variable $idTActi it's the id that i return from the second select, so when i click on the checkboxes and i send it on the button named class='carrito', that's an sprite that i generate on css, i see on the bottom another table with the information that i selected on the previous table:
echo "<div class='divPrecios'>";
echo "<table>";
echo "<tr class='tabPreciosTitles'>";
echo "<td>Nom Activitat</td>
<td>Nom Tipus Activitat</td>
<td>Tipus Tarifa</td>
<td>Temps/km</td>
<td>Preu</td>";
echo "</tr>";
foreach($_POST['checkbox'] as $item){
$stallTableCarrito=oci_parse($conn, "SELECT ACTIVIDAD.NOM AS NOM_ACTIVIDAD, TIPO_ACTIVIDAD.NOM AS NOM_TACTIVIDAD, TARIFAS.TIPO, TIPO_ACTIVIDAD.TEMPS_KM, TARIFAS.PRECIO
FROM TARIFAS, ACTIVIDAD, TIPO_ACTIVIDAD
WHERE TARIFAS.ID = $item
AND TARIFAS.ID_TIPO_ACTIVIDAD = TIPO_ACTIVIDAD.ID
AND TIPO_ACTIVIDAD.ID_ACTIVIDAD = ACTIVIDAD.ID");
oci_execute($stallTableCarrito);
$array=array(
0=>array(),
1=>array(),
2=>array(),
3=>array(),
4=>array()
);
while (($row=oci_fetch_array($stallTableCarrito,OCI_BOTH))!=false){
array_push($array[0],$row['NOM_ACTIVIDAD']);
array_push($array[1],$row['NOM_TACTIVIDAD']);
array_push($array[2],$row['TIPO']);
array_push($array[3],$row['TEMPS_KM']);
array_push($array[4],$row['PRECIO']);
}
for ($x=0;$x<count($array[0]);$x++){
echo "<tr>";
echo " <td>".$array[0][$x]."</td>";
echo " <td>".$array[1][$x]."</td>";
echo " <td>".$array[2][$x]."</td>";
echo " <td>".$array[3][$x]."</td>";
echo " <td>".$array[4][$x]."</td>";
echo " <td><input type='submit' class='carritoElim' value=''></td>";
echo "</tr>";
}
}
echo "</table>";
echo "</div>";
Basically that's a shopping form.
And where is the problem? When i send the pushed checkboxes with the button class='carrito', the form by default refresh the page and clears my array, what can i do?
In your first part of code, is your form tag open ? (I guess it is if this one works)
In the second part, is your <input type='submit' class='carritoElim' value=''> tag in a form ?
Because if it's not, you gonna have a bad time ;-)
Maybe in the last form you should generate hidden input with same names as your first form and same values.
If you don't I guess your variable $idTActi won't be set anymore and it won't succeed the first test if(isset($idTActi)). That could be why you get a cleared page.
If you have a multi step form in the same php page, for this kind of html code :
<form method=POST url="myURL">
<select name="select1">[...]</select>
<select name="select2">[...]</select>
<!-- VARIOUS PART : may not be displayed -->
<div id="checkboxes">
<input type="hidden" name="boxStep" value="1"/>
<input type="checkbox" name="cb1" value="1"/>
[...]
</div>
<!-- END OF VARIOUS PART -->
</form>
Then you need php tests in this order :
// if post request
if (isset($_POST)) {
if (isset($_POST['boxStep'])) {
// behavior when checkboxes values are sent
} else {
if (isset($_POST['select2'])) {
// behavior when second select is filled
// display "VARIOUS PART"
} else {
// behavior when only first select is filled
// Do not display "VARIOUS PART"
}
}
} else {
// default behavior (no select filled)
// Do not display "VARIOUS PART"
}

I have working code,
$output=json_encode($data);
$results=json_decode($output, TRUE);
foreach ($results['results'] as $id) {
echo $id['id'] . '<br/>';
}
But what i am trying to do is list not only the ID's of the JSON output but also the "subject" Associated with each ID right next or below it. not sure how to do so.
Try this
foreach ($results['results'] as $item) {
echo 'id: '. $item['id'] . ' subject: '. $item['subject'] .'<br/>';
}
echo "<form action=\"former.php\" method=\"post\">";
echo '<input type="text" name="TicketID" value="'. $item['id'] .'"/>';
echo "<input type=\"submit\" name=\"View\" value=\"View\" />";
the Above is working for me BUT it wont let me view the Specific ID . it just defaults to the last ID in the array. #veNuker
I have tried producing a form with the loop, when I process the input the checkbox values are not retrieving, it says invalid index.
Form:
for($i=0;$i<$count;i++){
echo '<td>';
echo '<input name="att[$i]" type="checkbox" id="att'.$i.'" value="1"/>';
echo '</td>';
echo '<td>';
echo '<input name="rno[$i]" type="text" id="rno'.$i.'"/>';
echo '</td>';
}
Retrieveing:
for($j=0;$j<$count;j++){
echo $rno=$_POST['rno'][$j];
echo $rno=$_POST['att'][$j];
}
I don't know where the problem is...
The error message invalid index "att". What is the problem?
It should be 'att' (string) rather than att:
for($j=0;$j<$count;j++){
echo $rno=$_POST['rno'][$j];
echo $rno=$_POST['att'][$j];
}
So this is part of my code :
echo "<form name='whatever' action='next.php' method='get'>";
while($row = mysql_fetch_assoc($qsq))
{
echo"<input type='checkbox' name='choice[]' value='" . $row['question_id'] . "' /> ". `$row['question_text'] . '<br />';`
}
echo"<br>";
echo "<input type='submit' value='submit' /></form>";
What should i do in the next.php ? I'm thinking to put the selected info in an array and display it. Then store the selected results in a table.But i am not sure with the codes.I am beginner in php can someone help me with the coding ?Thanks in advance!
First of all I cleaned up your code a little bit. (Using single quoutes around HTML trributes is uncanny).
echo ('<form name="whatever" action="next.php" method="get">');
while ($row = mysql_fetch_assoc ($qsq)) {
echo ('<input type="checkbox" name="choice[' . $row["question_id"] . ']" value="1" /> ' . $row["question_text"] . '<br />';
}
echo '<br />';
echo '<input type="submit" value="submit" /></form>';
Then you can iterate thru the values with a foreach loop in next.php.
echo ('<ul>');
foreach ($_GET["choice"] as $key => $value){
echo ('<li>' . $key . ' is ticked</li>');
}
echo ('</ul>');
Note that the array's keys hold the real information here,values wil only contain the number 1.
Take a look ath the source of resulting HTML. This is not theonly possible solution but good for learning purposes.
