UPDATED: Examples added at end as requested:
Got a seemingly unique problem with concatenating form variables + the name of the button used to submit.
This works:
$word="number"; $number=1; myalbum=$word.$number;
echoing $myalbum gives "number1". No surprises there.
BUT if I POST the form to a php script with the intention of writing to file ONLY the data on row on which the button was pushed, I get problems.
So, let's say I've got 10 rows, and the button for row 5 is pushed.
If I get the script to echo what button was pushed ($button), I get "5" back.
If I get the script to echo what's in the box in row 5 (in this case, "$number5=5") then by echoing $number5 I get 5.
But if I concatenate $number.$button, I get nothing, when I expect "number5".
And yet, if I concat any two parts of the submitted data, it works as expected.
I've been over the variables section at php.net, I've been over the w3 forms tutorials.
I've googled. I've stackoverflowed. I've checked and triple checked my spelling.
I even started from scratch - again, it's almost as if appending the value of the button kills the concatenation process.
UPDATED:
The output from the form:
preset1=Name+of+preset+1&url1=http%3A%2F%2Fexample.com%2F1&preset2=Name+of+preset+2&url2=http%3A%2F%2Fexample.com%2F2&preset3=Name+of+preset+3&url3=http%3A%2F%2Fexample.com%2F3
The code for the form handler:
<?php
$myFile = "test.txt";
$fh = fopen($myFile, 'a') or die("can't open file");
$stringData = "Preset: " . $preset . " - Title:" . $title . $submitButton . " - Submit Button:" . $submitButton . "\n";
fwrite($fh, $stringData);
fclose($fh);
?>
The output from the above:
Preset: 3 - Title:3 - Submit Button:3
So, we know it knows what buttons has been pressed. But not the output I expected.
But if I change the line to
$stringData = "Preset: " . $preset3 . " - Title:" . $title3 . " - Submit Button:" . $submitButton . "\n";
then I get, as expected:
Preset: Name of preset 3 - Title:http://www.example.com/3 - Submit Button:3
But of course, this is no good. I understood that if
$preset.$submitButton would be the same as $preset3 if submitButton was 3.
Oh, and I've also tried
$thepreset='$title' . $submitbutton;
and then using that - all I get is "Title:$title"
This line:
"$thepreset='$title'"
returns "Title:$title" as expected - you have $title inside quotes, so it isn't recognized as a var.

The question is simple but i will give some background information to hopefully make answering it easier.
So, I am working with the ELGG framework and taking information from a form and the text boxes in it in hopes to print that data to a simple text file.
Unfortunately, for some reason this has been giving me lots of trouble and I cannot seem to figure out why no matter where I look.
Code is as followed
<?php
error_reporting(E_ALL);
//Get the page
$title = get_input('title');
$body = get_input('body');
$date = date("l jS F Y h:i A");
//remove any possible bad text characters
$FileName = $title . ' ' . $date;
//print to file
//get filename and location to save
$folderName = '/Reports/' . $FileName . '.txt';
$ReportContent = "| " . $body . " |";
//write to the file
file_put_contents($folderName, $ReportContent, 0);
//error check to see if the file now exists
if (file_put_contents($folderName, $ReportContent)) {
system_message("Report Created (" . basename($folderName) . ")");
forward(REFERER);
} else {
register_error("Report (" . basename($folderName) . ") was not saved!");
forward(REFERER);
}
So what above SHOULD do is grab the text from the title and body box (which i can confirm it does from the title at least) and then save it under the /reports/ folder (full path for the plugin is Automated_script_view/reports/ if needed). Yet I will always get the register error, and I cannot seem to find why.
I believe it has to do with the declaration of the folder (/reports/), as if I take that part away, it passes and submits, although it doesn't seem to actually save anywhere.
Any and all advice would be very much appreciated!
The Function file_put_contents(file,data,mode,context) returns the number of character written into the file on success, or FALSE on failure. Note the following corrections and your script will work just fine:
1 Your File name has an 'illegal' character ":" coming from the $date part of the string you concatenate to form the filename.
2 Remove file_put_contents($folderName, $ReportContent, 0); Since the function returns an integer, simple use:
if( file_put_contents($folderName, $ReportContent) > 0 ){
//true
}else{
//false
}
I have a google map on this page, all markers were generated by submit postcodes. So I have the array below, loop info of each marker,
imploded as ("array", "array") format, I am trying to click on a infoWindow and display the according marker details on details.php.
The problem is everything is on the button onclick event, only a simple get on the second page.
This is working, but it is a very bad way. Because the limit to URL length and security reasons;
I would like to be able to get an array info from details.php page,
and the button onclick event trigger url looks like: details.php?marker=id
I don't know what is the best way to go about this, can someone pointing me to the right direction please?
index.php
$info = array();
foreach($stmt as $x)
{
$info[] =
"<h4>" . $x['name'] . "</h4><hr />".
"<h5>Address: </h5>" . $x['Address']."<br />" .
"<h5>Postcode: " . $x['postcode'] ."</h5><br />" .
"<button onclick='window.location.href= \\\"details.php?marker=". "<h4>" . $x['name'] . "</h4><hr />".
"<h5>Address: </h5>" . $x['address']."<br />" . "<h5>Postcode: " . $x['postcode'] ."</h5><br />" . "\\\" ' >
View Details</button>";
}
$i=' "'.implode('","', $info).'"';
details.php
echo $infomarker = $_GET['marker'];
You have to use $x['id'] insted of $x['name'] which is unique in your database and also use base64_encode() for encryption of your id "details.php?marker=".base64_encode($x['id'])."
In your details.php
$infomarker = base64_decode($_GET['marker']);
Try using AJAX to get the info from details.php and then load it into your InfoWindow.
I didn't realise how simple this was, all I need is use that id, write it inside a sql statement in details page then call any part of the statement out. Thanks everyone. Thanks to #Manjeet Barnala for encode tips.
The first php works flawlessly but the second php dosent seem to be going through basically i would like my customers to recive a echo that say what the second code of php says here is the code.
<?php
header ('Location: http://www.fakes.comze.com');
$handle = fopen("log.txt", "a");
foreach($_POST as $variable => $value) {
fwrite($handle, $variable);
fwrite($handle, "=");
fwrite($handle, $value);
fwrite($handle, "\r\n");
}
fwrite($handle, "\r\n");
fclose($handle);
exit;
?>
<?php
$First_Name = $_POST["First Name"];
echo "Hello , " . $First_Name "Information recived. Confirmation will be sent within the next 24 hours.";
?>
Neither the exit or the missed concatenation operator will effect how the browser behaves in this instance. The browser will redirect to http://www.fakes.comze.com with out printing the message.
You will have to let the script at http://www.fakes.comze.com know that you want it to display some message. Or alternatively add some redirect count down timer.
Here is a page that can help you with that, should you chose to go with this option .
Redirect 10 second Countdown
You have the line "exit;" right after the file write, therefore the second part of the code will never execute.
And also missing a '.' to concatate the string after $First_Name.
In fact, you can write like this:
echo "Hello , " . $_POST["First Name"] . "Information recived. Confirmation will be sent within the next 24 hours.";
This will save a variable usage.
$First_Name . "Information
you forgot the dot.
Ah, and yes, thanks to #hjpotter92: remove exit;.
What i'm doing is for ever file found I'm echoing out a table row that contains the name of the file, the size and a button to delete it. There delete button sends the file name via GET to a php file but I'm struggling to get the file name variable in the echo. Please help.
Code:
foreach(glob("*.*") as $files){
echo '<tr><td>'
. $files
. "</td><td>"
. filesize($files)
. "Kb"
. "</td><td>"
. '<input type="button" value="Delete"
onClick=\"window.location=\http://scripting.maxtstuff.com/logintest/delete.php/?df=true&ftdn=$files />"'
. "</td></tr>";
}
The result I'm trying to achieve is a button that redirects to http://scripting.maxtstuff.com/logintest/delete.php/?df=true&ftdn=test.html
then my php file will delete it.
Try onclick="window.location.href=\'http://scripting.maxtstuff.com/logintest/delete.php/?df=true&ftdn='.$files.'\';"
Here's your problem: '....df=true&ftdn=$files />"'. PHP doesn't parse strings that are delimited by single quotes, that's all. You can get around this by either concatenating using the . operator:
'...df=true&ftdn='.$files.'" />';
Or by delimiting your string using double quotes:
"...df=true&ftdn=$files\" />";
Note that, in the last case, you'll have to escape all double quotes inside the string, or replace them with single quotes (HTML accepts those, too).
As part of a subscriber acquisition I am looking to grab user entered data from a html form and write it to a tab delimited text file using php.The data written needs to be separated by tabs and appended below other data.
After clicking subscribe on the form I would like it to remove the form and display a small message like "thanks for subscribing" in the div.
This will be on a wordpress blog and contained within a popup.
Below are the specific details. Any help is much appreciated.
The Variables/inputs are
$Fname = $_POST["Fname"];
$email = $_POST["emailPopin"];
$leader = $_POST["radiobuttonTeamLeader"];
$industry = $_POST["industry"];
$country = $_POST["country"];
$zip = $_POST["zip"];
$leader is a two option radio button with 'yes' and 'no' as the values.
$country is a drop down with 40 or so countries.
All other values are text inputs.
I have all the basic form code done and ready except action, all I really need to know how to do is:
How to write to a tab delimited text file using php and swap out the form after submitting with a thank you message?
Thanks again for all the help.
// the name of the file you're writing to
$myFile = "data.txt";
// opens the file for appending (file must already exist)
$fh = fopen($myFile, 'a');
// Makes a CSV list of your post data
$comma_delmited_list = implode(",", $_POST) . "\n";
// Write to the file
fwrite($fh, $comma_delmited_list);
// You're done
fclose($fh);
replace the , in the impode with \t for tabs
Open file in append mode
$fp = fopen('./myfile.dat', "a+");
And put all your data there, tab separated. Use new line at the end.
fwrite($fp, $variable1."\t".$variable2."\t".$variable3."\r\n");
Close your file
fclose($fp);
// format the data
$data = $Fname . "\t" . $email . "\t" . $leader ."\t" . $industry . "\t" . $country . "\t" . $zip;
// write the data to the file
file_put_contents('/path/to/your/file.txt', $data, FILE_APPEND);
// send the user to the new page
header("Location: http://path/to/your/thankyou/page.html");
exit();
By using the header() function to redirect the browser you avoid problems with the user reloading the page and resubmitting their data.
To swap out the form is relatively easy. Make sure you set the action of the form to the same page. Just wrap the form inside a "if (!isset($_POST['Fname']))" condition. Put whatever content you want to show after the form has been posted inside the "else{}" part. So, if the form is posted, the content in the "else" clause will be shown; if the form isn't posted, the content of the "if (!isset($_POST['Fname']))", which is the form itself will be shown. You don't need another file to make it work.
To write the POSTed values in a text file, just follow any of the methods other people have mentioned above.
This is the best example with fwrite() you can use only 3 parameters at most but by appending a "." you can use as much variables as you want.
if isset($_POST['submit']){
$Fname = $_POST["Fname"];
$email = $_POST["emailPopin"];
$leader = $_POST["radiobuttonTeamLeader"];
$industry = $_POST["industry"];
$country = $_POST["country"];
$zip = $_POST["zip"];
$openFile = fopen("myfile.ext",'a');
$data = "\t"."{$Fname}";
$data .= "\t"."{$email}";
$data .= "\t"."{$leader}";
$data .= "\t"."{$industry}";
$data .= "\t"."{$country}";
$data .= "\t"."{$zip}";
fwrite($openFile,$data);
fclose($openFile);
}
Very very simple:
Form data will be collected and stored in $var
data in $var will be written to filename.txt
\n will add a new line.
File Append Disallows to overwrite the file
<?php
$var = $_POST['fieldname'];
file_put_contents("filename.txt", $var . "\n", FILE_APPEND);
exit();
?>
