Hi guys I know I am asking a common question but in my case I have the following code:
if (!isset($_SESSION['countRows']) && empty($_SESSION['countRows']))
{
$_SESSION['countRows'] = $_POST['countRows'];
}
$data = date("dmY");
$filename = "EstrazioneParziale_del_" . $data;
$estensione = ".csv";
$fileOpen = fopen($filename.$estensione, "a") or die("Impossibile aprire il file");
$arrayData = ['Operation','Nome Servizio','ID Servizio','S.O.','Patch Level','N° Apparati'];
fputcsv($arrayData, array_keys($_POST['arrayFiltrato'][0]));
foreach ($_POST['arrayFiltrato'] as $fields) {
fputcsv($fileOpen, $fields);
}
fclose($file);
The first fputcsv doesn't insert an header to the csv file and I only can see the csv file will all the datas without the header (I use $arrayData to get the headers). Can somebody help me? Many thanks! :-)
Your call to put the headers out doesn't use the right parameters, the first is the file handle and the second is the data. So...
fputcsv($arrayData, array_keys($_POST['arrayFiltrato'][0]));
should be
fputcsv($fileOpen,$arrayData);
Also you probably want to open the file in write mode instead of append (otherwise your new content will be added to the end of the existing content)...
$fileOpen = fopen($filename.$estensione, "w") or die("Impossibile aprire il file");
Your close is using the wrong file handle as well...
fclose($file);
should be
fclose($fileOpen);

I need your help.
I need to every time the code stores the information in txt file, then each new record to the new line and what should be done to all be numbered?
<?php
$txt = "data.txt";
if (isset($_POST['Password'])) { // check if both fields are set
$fh = fopen($txt, 'a');
$txt=$_POST['Password'];
fwrite($fh,$txt); // Write information to the file
fclose($fh); // Close the file
}
?>
Added some comments to explain the changes.
<?php
$file = "data.txt"; // check if both fields are set
$fh = fopen($file, 'a+'); //open the file for reading, writing and put the pointer at the end of file.
$word=md5(rand(1,10)); //random word generator for testing
fwrite($fh,$word."\n"); // Write information to the file add a new line to the end of the word.
rewind($fh); //return the pointer to the start of the text file.
$lines = explode("\n",trim(fread($fh, filesize($file)))); // create an array of lines.
foreach($lines as $key=>$line){ // iterate over each line.
echo $key." : ".$line."<br>";
}
fclose($fh); // Close the file
?>
PHP
fopen
fread
explode
You can do like this in a more simpler way..
<?php
$txt = "data.txt";
if (isset($_POST['Password']) && file_exists($txt))
{
file_put_contents($txt,$_POST['Password'],FILE_APPEND);
}
?>
we open file to write into it ,you must make handle to a+ like php doc
So your code will be :
<?php
$fileName = "data.txt"; // change variable name to file name
if (isset($_POST['Password'])) { // check if both fields are set
$file = fopen($fileName, 'a+'); // set handler to a+
$txt=$_POST['Password'];
fwrite($file,$txt); // Write information to the file
fclose($file); // Close the file
}
?>
So I have a JSON file containing basketball player information in the following format:
[{"name":"Lamar Patterson","team":1,"yearsLeft":0,"position":"PG","PPG":17},{"name":"Talib Zanna", "team":1,"yearsLeft":0,"position":"SF","PPG":13.1},....]
I want a user to be a able to add their own custom players to this file. To do this i try the following:
<?php
$json = file_get_contents('json/players.json');
$info = json_decode($json, true);
$info[] = array('name'=>$name, 'team'=>$team, 'yearsLeft'=>4, 'position'=>$position, 'PPG'=>$ppg);
file_put_contents('json/players.json', json_encode($info));
?>
This "sort of" works. But when I check the JSON file, I find that there are 3 new entries rather than 1:
{"name":"","team":null,"yearsLeft":4,"position":"","PPG":""},{"name":"","team":"3","yearsLeft":4,"position":"","PPG":""},{"name":"Jeff","team":null,"yearsLeft":4,"position":"C","PPG":"23"}
assuming $name="Jeff" $team=3 and $ppg=23 (populated via POST submission).
What's going on and how can I fix it?
You could try doing the following:
Untested code
<?php
if(!empty($name) && !empty($team) && !empty($position) && !empty($ppg)) {
$fh = fopen('json/players.json', 'r+') or die("can't open file");
$stat = fstat($fh);
ftruncate($fh, $stat['size']-1);//removes last ] char
fclose($fh);
$fh = fopen('json/players.json', 'a');
$info = array('name'=>$name, 'team'=>$team, 'yearsLeft'=>4, 'position'=>$position, 'PPG'=>$ppg);
fwrite($fh, ','.json_encode($info).']');
fclose($fh);
}
?>
This will append the only the new json to the file instead of opening the file, making php parse all the json and then writing it to the file again. In addition to that it will only store the data if the variables actually contain data.
Try this:
<?php
//get the posted values
$name = $_POST['name'];
$team = $_POST['team'];
$position = $_POST['position'];
$ppg = $_POST['ppg'];
//verify they're not empty
if(!empty($name) && !empty($team) && !empty($position) && !empty($ppg)) {
//Open the file
$fh = fopen('json/players.json', 'r+') or die("can't open file");
//get file info/stats
$stat = fstat($fh);
//final desired size after trimming the trailing ']'
$size = $stat['size']-1;
//file has contents? then remove the trailing ']'
if($size>0) ftruncate($fh, $size);
//close the current handle
fclose($fh);
// reopen the file for append
$fh = fopen('json/players.json', 'a');
//build your data array
$info = array('name'=>$name, 'team'=>$team, 'yearsLeft'=>4, 'position'=>$position, 'PPG'=>$ppg);
//if this is not the first item on file
if($size>0) fwrite($fh, ','.json_encode($info).']'); //append with comma
else fwrite($fh, '['.json_encode($info).']'); //first item on file
fclose($fh);
}
?>
Maybe your php config is not set to convert the post/get variables to global variables. This happened to me a couple of times so I rather create the variables I'm expecting from the post/get request. Also watch out for the page encoding, from personal experience you could be getting empty strings there.
Ok I almost have it working but am having trouble escaping the html to preserve the link I'm missing something here .. I'm sure it's simple
if($_POST['formSubmit'] == "Submit")
$varUserName = $_POST['username'];
$varPW = $_POST['PW'];
$varEmail = $_POST['email'];
{
$fs = fopen("testcsv.csv","a");
fputcsv($fs, array($varUserName,$varPW,$varEmail,"admin","title",",category","some text here site.com",));
fclose($fs);
exit;
}
?>
I am not sure what you're having trouble with. Are you familiar with fopen();? Are you familiar with CSV?
You will need to open the file for appending and append to your file using fwrite(). Once done, close the file with fclose().
$fp = fopen("./filename", 'a'); //Open file for append
//fwrite($fp, $row1.",".$row2); //Append row,row to file
fputcsv($fp, array($name,$password,"http://$name.whatever.com")); //#Optimist
fclose($fp); //Close the file to free memory.
I create form to load sql file and used fopen function top open file and read this but when want to execute this data to database not work?
What is wrong in my code?
$ofile = trim(basename($_FILES['sqlfile']['name']));
$path = "sqlfiles/".$ofile;
//$data = settype($data,"string");
$file = "";
$connect = mysql_connect('localhost','root','');
$selectdb = mysql_select_db('files');
if(isset($_POST['submit']))
{
if(!move_uploaded_file($_FILES['sqlfile']['tmp_name'],"sqlfiles/".$ofile))
{
$path = "";
}
$file = fopen("sqlfiles/".$ofile,"r") or exit("error open file!");
while (!feof($file))
{
$data = fgetc($file);
settype($data,"string");
$rslt = mysql_query($data);
print $data;
}
fclose($file);
}
maybe you should use fgets instead of fgetc while youre reading lines.
Your script assumes that there is exactly one SQL statement per line, with no blanks or comments. If this is not the case then you'll need to either read and parse the file manually, or redirect the file to the mysql executable and let it handle the SQL statements.
I have:
<?php
$file=fopen(date("Y-m-d").".txt","r+") or exit("Unable to open file!");
if ($_POST["lastname"] <> "")
{
fwrite($file,$_POST["lastname"]."\n");
}
fclose($file);
?>
but it overwrites the beginning of the file. How do I make it insert?
I'm not entirely sure of your question - do you want to write data and not have it over-write the beginning of an existing file, or write new data to the start of an existing file, keeping the existing content after it?
To insert text without over-writing the beginning of the file, you'll have to open it for appending (a+ rather than r+)
$file=fopen(date("Y-m-d").".txt","a+") or exit("Unable to open file!");
if ($_POST["lastname"] <> "")
{
fwrite($file,$_POST["lastname"]."\n");
}
fclose($file);
If you're trying to write to the start of the file, you'll have to read in the file contents (see file_get_contents) first, then write your new string followed by file contents to the output file.
$old_content = file_get_contents($file);
fwrite($file, $new_content."\n".$old_content);
The above approach will work with small files, but you may run into memory limits trying to read a large file in using file_get_conents. In this case, consider using rewind($file), which sets the file position indicator for handle to the beginning of the file stream.
Note when using rewind(), not to open the file with the a (or a+) options, as:
If you have opened the file in append ("a" or "a+") mode, any data you write to the file will always be appended, regardless of the file position.
A working example for inserting in the middle of a file stream without overwriting, and without having to load the whole thing into a variable/memory:
function finsert($handle, $string, $bufferSize = 16384) {
$insertionPoint = ftell($handle);
// Create a temp file to stream into
$tempPath = tempnam(sys_get_temp_dir(), "file-chainer");
$lastPartHandle = fopen($tempPath, "w+");
// Read in everything from the insertion point and forward
while (!feof($handle)) {
fwrite($lastPartHandle, fread($handle, $bufferSize), $bufferSize);
}
// Rewind to the insertion point
fseek($handle, $insertionPoint);
// Rewind the temporary stream
rewind($lastPartHandle);
// Write back everything starting with the string to insert
fwrite($handle, $string);
while (!feof($lastPartHandle)) {
fwrite($handle, fread($lastPartHandle, $bufferSize), $bufferSize);
}
// Close the last part handle and delete it
fclose($lastPartHandle);
unlink($tempPath);
// Re-set pointer
fseek($handle, $insertionPoint + strlen($string));
}
$handle = fopen("file.txt", "w+");
fwrite($handle, "foobar");
rewind($handle);
finsert($handle, "baz");
// File stream is now: bazfoobar
Composer lib for it can be found here
You get the same opening the file for appending
<?php
$file=fopen(date("Y-m-d").".txt","a+") or exit("Unable to open file!");
if ($_POST["lastname"] <> "")
{
fwrite($file,$_POST["lastname"]."\n");
}
fclose($file);
?>
If you want to put your text at the beginning of the file, you'd have to read the file contents first like:
<?php
$file=fopen(date("Y-m-d").".txt","r+") or exit("Unable to open file!");
if ($_POST["lastname"] <> "")
{
$existingText = file_get_contents($file);
fwrite($file, $existingText . $_POST["lastname"]."\n");
}
fclose($file);
?>
