My main question is why is PDO::exec not executing every iteration of my loop, and instead only executing in the first iteration.
I am trying to insert coordinates into my MySQL database.
My database structure is (number(primary key), x, y, z).
I ask the user to insert a number ($n), and then ask them to fill in $n sets of coordinates.
The users inputs are passed to another page with $_POST, then retrieved by dynamic variable names and inserted into the database.
Everything works, except the loop only writes to the database its first iteration. So I end up with results for x1,z1,y1 but nothing else.
Can anyone explain what I am doing wrong (other than not using arrays)?
<?php
require_once('db.php');
$n = $_POST['selectOption'];
for($i = 1; $i < $n+1;$i++){
${'x' . $i} = $_POST["x" . $i];
${'y' . $i} = $_POST["y" . $i];
${'z' . $i} = $_POST["z" . $i];
$rowsAffected = $db->exec("INSERT INTO coordinate3d (number,x,y,z)
VALUES ('$n', '${'x' . $i}', '${'y' . $i}', '${'z' . $i}')");
}
?>
Here is my form
<form action="aaron_stockdale_dynamic_process.php" method="post" name="coordinateForm">
<?php
for($i = 0; $i < $n; $i++)
{
?>
x<?php echo $i+1;?> <input name="x<?php echo $i+1;?>" type=text>, y<?php echo $i+1;?> <input name="y<?php echo $i+1;?>" type=text>, z<?php echo $i+1;?> <input name="z<?php echo $i+1;?>" type=text><br>
<?php
}
?>
<br>
<input type="hidden" name="selectOption" value="<?php echo $n;?>">
<input type="submit" oonClick="document.location.href='aaron_stockdale_dynamic_process.php'" value="Submit">
</form>
require_once('aaron_stockdale_database.php');
$n = $_POST['selectOption'];
for($i = 1; $i < $n+1;$i++){
$x = $_POST["x" . $i];
$y = $_POST["y" . $i];
$z = $_POST["z" . $i];
$rowsAffected = $db->exec("INSERT INTO coordinate3d (number,x,y,z)
VALUES ('$n', '$x', '$y', '$z')");
}
the rest is on you ;)
And also check if any of the fields a primary key, that will prevent insert it twice.
Since you have received an acceptable answer for your question, I'd like to give you a hint on your html code.
<form action="aaron_stockdale_dynamic_process.php" method="post" name="coordinateForm">
<?php
for($i = 0; $i < $n; $i++)
{
?>
x<?php echo $i+1;?> <input name="x<?php echo $i+1;?>" type=text>, y<?php echo $i+1;?> <input name="y<?php echo $i+1;?>" type=text>, z<?php echo $i+1;?> <input name="z<?php echo $i+1;?>" type=text><br>
<?php
}
?>
<br>
<input type="hidden" name="selectOption" value="<?php echo $n;?>">
<input type="submit" oonClick="document.location.href='aaron_stockdale_dynamic_process.php'" value="Submit">
</form>
Now, this code can be cleaned up a bit.
<form action="aaron_stockdale_dynamic_process.php" method="post" name="coordinateForm">
<?php
for($i = 0; $i < $n; $i++)
{
echo 'x' . $i+1 . '<input name="x' . $i+1 . '" type=text>, y' . $i+1 . ' <input name="y' . $i+1. '" type=text>, z' . $i+1 . '<input name="z' . $i+1 . '" type=text><br>'
}
?>
<br>
<input type="hidden" name="selectOption" value="<?php echo $n;?>">
<input type="submit" value="Submit">
</form>
I changed the "oonClick" to "onClick", and then afterwards I removed it, as when you submit, you don't need to navigate, as the browser will do this, upon submission.
And then I removed the repetitive opening and closing of php tags, and combined all the echos into one.
Here's my solution in one file:
<!DOCTYPE html>
<html lang=en>
<head>
<script>
function validcoord(e) {
var key;
var keychar;
if (window.event)
key = window.event.keyCode;
else if (e)
key = e.which;
else
return true;
keychar = String.fromCharCode(key);
keychar = keychar.toLowerCase();
// control keys
if ((key==null) || (key==0) || (key==8) || (key==9) || (key==13) || (key==27) )
return true;
// Numeral Characters
else if ((("0123456789-.,").indexOf(keychar) > -1))
return true;
else
return false;
}
</script>

Can anyone help me with the pagination? I am trying this code on pagination and the pages are showing but when clicked on the pages like Next or the number with links it gives a syntax error.

You have error on html URL syntax
echo 'NEXT';
The correct would be
echo 'NEXT';
You have to use ? only for the first URL parameter, & for the following, if any.
I wonder how I can make sure a checkbox is checked on a postback if for example someone leaves the addressfield blank it should then make sure the user doesn't have to refill the whole form again. In this case I'm generating 31 checkboxes. It's really frustrating.
$output_checkbox = '';
$checked = '';
for ($i=1; $i <= 31; $i++) {
if (isset($_POST['dagen'])) {
foreach ($_POST['dagen'] as $dag) {
if ($dag == $i) {
$checked . $i = 'checked';
}
}
}
$output_checkbox .= '<input type="checkbox" name="dagen[]" value="' . $i . '" id="day_' . $i . '"' . $checked . ' /><label for="day_' . $i . '">Dag ' . $i . '</label>';
}
Here is the form but there isn't the problem:
<form action="<?php echo $_SERVER['REQUEST_URI']; ?>" method="post">
<div>
<label for="email">Email:</label>
<input id="email" type="text" name="email" value="<?php if(isset($_POST['email'])) { echo $_POST['email'];} ?>" />
</div>
<div>
<label for="month">Maand:</label>
<select id="month" name="month">
<?php echo $output; ?>
</select>
</div>
<div>
Dagen:
<?php echo $output_checkbox; ?>
</div>
<input type="submit" name="btnSend" value="Verzenden" />
</form>
Here is an example of how I normally do it but it's a lot easier since it comes out of a database:
$output = '';
while ($row = $result->fetch_array(MYSQLI_BOTH)) {
$selected = '';
if (isset($_POST['month']) && $_POST['month'] == $row['id']) {
$selected = 'selected';
}
$output .= '<option value="' . $row['id'] . '"' . $selected . '>' . $row['naam'] . '</option>';
}
Something like this:
$output_checkbox = '';
for ($i=1; $i <= 31; $i++) {
if (isset($_POST['dagen'])) {
foreach ($_POST['dagen'] as $dag) {
if ($dag == $i) {
$checked = 'checked';
}
else{
$checked = '';
}
$output_checkbox .= '<input type="checkbox" name="dagen[]" value="' . $i . '" id="day_' . $i . '"' . $checked . ' /><label for="day_' . $i . '">Dag ' . $i . '</label>';
}
}
}
I have while loop to get information from mysql table. But can't figure how to find las entry containing same factor_id and add append new element after it.
if ($this->_db->numRows() > 0) {
$i = 1;
$j = '';
$row = '';
while ($row = mysqli_fetch_assoc($res_info)) {
if ($row['task_factor_category'] != $j) {
$title = '<tr><td colspan="4" class="title" style="text-align: left;">' . $row['task_factor_category'] . '</td></tr>';
$comment = '<tr><td class="title" style="text-align: left" colspan="4">' . $this->_glan['comments'] . '</td></tr><tr><td colspan="4"><textarea cols="82" rows="3" name="factor_comment[' . $row['factor_id'] . ']" id="' . $row['factor_id'] . '"></textarea></td></tr>';
} else {
$title = false;
$comment = false;
}
$this->reg['edit_fields']['factors'] .= $title . '<tr>
<td>
' . $row['factors'] . '
</td>
<td>
<input type="radio" name="task_factor[' . $i . '_' . $row['factor_id'] . ']" value="1" />
</td>
<td>
<input type="radio" name="task_factor[' . $i . '_' . $row['factor_id'] . ']" value="2" checked />
</td>
<td>
<input type="radio" name="task_factor[' . $i . '_' . $row['factor_id'] . ']" value="3" />
</td>
</tr>
';
$j = $row['task_factor_category'];
$i++;
}
}
output is like:
//results with $row['factor_id'] = 10;
title
1. entry
2. entry
3. entry
4. entry
5. entry
//need new element here
//results with $row['factor_id'] = 11;
title
1. entry
2. entry
3. entry
4. entry
5. entry
//need new element here
......
I need to add additional element after the last entry containing same factor id
You may want to try this one.
$id = array();
$i = 0;
while ($row = mysqli_fetch_assoc($res_info))
{
$id[$i] = $row['id'];
if ($i != 0 && $id[$i-1] != $row['id']) {
//new element
} else {
//same element
}
$i++
}
you can count total rows suppose there are 7 rows
Add a if code in while loop like
while(cond)
{
if($i == 7 )
{
then echo("what ever you want");
}
}
I am new to php and form development and here's what I am trying to achieve:
Firstly i have a simple form to input just two text values:
Form1
<br>
<form action="gather.php" method="post">
Catalog:
<input type="text" name="folderName" maxlength="50">
<br>
File Name:
<input type="text" name="fileName" maxlength="50">
<br>
<input type="submit" name="formSubmit" value="Submit">
</form>
And now I have the second file called gather.php where i get theese two lines and use them to count files inside catalog etc.
<?php
if(isset($_POST['formSubmit'])){
$folderName = $_POST['folderName'];
$fileName = $_POST['fileName'];
$numberOfImages = count(glob($folderName . "/*.jpg"));
for($i = 1; $i <= $numberOfImages; $i++){
echo "<br><input type=\"text\" name=\"imie" . $i . "\"><br/>\n";
echo "<img src=\"" . $folderName . "/0" . $i . ".jpg\" height=\"50px\" width=\"50px\"><br><br>\n";
}
echo "\n<br>" . $folderName . "<br>" . $fileName . "\n";
}
?>
<br>
Final form
<br>
<form action="build.php" method="post">
<input type="submit" name="finalSubmit" value="Submit">
</form>
And this should get me to build.php file which looks more less like this:
<?php
if(isset($_POST['finalSubmit'])){
//loop and other stuff
$temp = $_POST['imie1'];
echo $temp;
}
?>
So the thing is that in this final file I'd like to get all the data that was put into text fields in the gather.php file. But I get the undefined index error on build.php saying there's nothing in the $_POST['imie1']. Can you tell me why is that? Is tehre a way to get this data from second file to the third file?
Edit: thx for the answers, as I can accept only 1 and multiple are the same I choose the user with least rep just to support her :)
You need to add the input inside the form tag, it won't be sent otherwise.
<br>
Final form
<br>
<form action="build.php" method="post">
<?php
if(isset($_POST['formSubmit'])){
$folderName = $_POST['folderName'];
$fileName = $_POST['fileName'];
$numberOfImages = count(glob($folderName . "/*.jpg"));
for($i = 1; $i <= $numberOfImages; $i++){
echo "<br><input type=\"text\" name=\"imie" . $i . "\"><br/>\n";
echo "<img src=\"" . $folderName . "/0" . $i . ".jpg\" height=\"50px\" width=\"50px\"><br><br>\n";
}
echo "\n<br>" . $folderName . "<br>" . $fileName . "\n";
}
?>
<input type="submit" name="finalSubmit" value="Submit">
</form>
Replace your gather.php with
<br>
Final form
<br>
<form action="build.php" method="post">
<?php
if(isset($_POST['formSubmit'])){
$folderName = $_POST['folderName'];
$fileName = $_POST['fileName'];
$numberOfImages = count(glob($folderName . "/*.jpg"));
for($i = 1; $i <= $numberOfImages; $i++){
echo "<br><input type=\"text\" name=\"imie" . $i . "\"><br/>\n";
echo "<img src=\"" . $folderName . "/0" . $i . ".jpg\" height=\"50px\" width=\"50px\"><br><br>\n";
}
echo "\n<br>" . $folderName . "<br>" . $fileName . "\n";
}
?>
<input type="submit" name="finalSubmit" value="Submit">
</form>
you was echo'ing the input boxes outside the form so now it will work
I think the <form> on the second form needs to come at the top of the file - it'll only submit elements inside the tag, so because you're generating your HTML and then opening the form, it's not being submitted.
<br>
Final form
<br>
<form action="build.php" method="post">
<?php
if(isset($_POST['formSubmit'])){
$folderName = $_POST['folderName'];
$fileName = $_POST['fileName'];
$numberOfImages = count(glob($folderName . "/*.jpg"));
for($i = 1; $i <= $numberOfImages; $i++){
echo "<br><input type=\"text\" name=\"imie" . $i . "\"><br/>\n";
echo "<img src=\"" . $folderName . "/0" . $i . ".jpg\" height=\"50px\" width=\"50px\"><br><br>\n";
}
echo "\n<br>" . $folderName . "<br>" . $fileName . "\n";
}
?>
<input type="submit" name="finalSubmit" value="Submit">
</form>
Here's the form handling
if(isset($_POST['clear'])) {
mysql_query("DELETE FROM md5dictionary");

<?php echo $errors['blank']; ?>
<input name="keywords" type="text" />
<input name="submit" type="submit" value="Add!!" />
<input name="clear" type="submit" value="Clear Database" />
</form>
<h1> Datas: </h1>
<?php
$result = mysql_query("SELECT * FROM md5dictionary");
$rows = mysql_num_rows($result);
for ($i = 0; $i < $rows; ++$i) {
echo "Data " . $i . "<br />";
echo "keywords: " . mysql_result($result, $i, "keywords") . "<br />";
echo "md5: " . mysql_result($result, $i, "mdFive") . "<br />";
echo "md5_2: " . mysql_result($result, $i, "mdFive2") . "<br />";
}
?>

Question: Why it keeps saying "Failed!" Why it has successfully insert information into my database?
There should be no spelling mistake
I know it will be time-consuming go through my dumb question but plss, i can't explain it myself!!
I've tested the weblink you provided.
If I insert a word then I get 'inside else' and it looks like it's inserted.
If I quickly enter this word again then I get 'failed'.
So I see no problem, isn't this what you want to achieve ?
Otherwise please rethink your question and refine what is not working for you and when.
EDIT:
If you want the successful message then you need another:
echo $finalResult;
after you defined $finalResult.
I'm not sure about what you mean when you say it inserts and it gives "fail".
Do you actually mean "INSERT INTO md5dictionary..." is executed, AND you have the " Failed!!! " code showing?
If this is so, I recommend you investiguate and revise your form flows since it is most probable that calling itself, the form tries to run twice, the second time having null values.
This is what I coming up with.
Have a good day,
