My code is some complicated, it is done in codeigniter. I mentioned the code below, but pls give me a complete simple code in php as seperate file.

and this code has validation of phonenumber, account number etc. I just need to update only the date field curresponding customer account number.
thank you ...

Hang on. You said in your previous post that you have data in mysql table which you want to update, or have I missunderstood the question.

So do you want to update a row in an excel sheet? I do not hink you could do that. You have to read in the whole file, find the row to change and write the whole file back, as far as I know. But I could be werong so maybe anyone else knows?

0

Yes, I have already exprted datas in to mysql table. But the one of the date field formate has been changed when export excel sheet. So i need to update only date field in mysql table by reading the same excel sheet. But the other datas except that date field shoudnot be changed.

Please help me.
Thanks in advance.

OK, how is the date written in Excel and how you want to have it written in mysql? Post an example if possible.

0

in excel written as dd/mm/yy. didnt change the format like mm-dd-yy. That may be chnanged the date.
Now the date has been change to 1970-01-01 , not getting actual date.

0

If dates in Excel are formatted as dd/mm/yy (allways) you can use the following function on each date during the import or write to database:

function reformatDate($theDate) {

    // get the parts of the date
    $day = substr($theDate, 0, 2);
    $month = substr($theDate, 3, 2);
    $year = substr($theDate, 6, 2);

    // return the parts in different order and separated by dash
    return "$month-$day-$year";
}

[EDIT] or even better:

function reformatDate($theDate) {

    // explode date string into array
    $dateArr = explode('/', $theDate);

    // return string with reordered elements
    return "{$dateArr[1]}-{$dateArr[0]}-{$dateArr[2]}";
}

Thank you....
but pls tell me how to read one particular field (here "sale_date') from excel sheet when importing?

0

Pass the above function the appropriate element of the array, containing the excel data. Maybe something like this:

$correctDate = reformatDate($this->spreadsheet_excel_reader->sheets[0]['cells'][1]['sale_date']);

I am just guessing this since I do not know the structure of the excel reader class.

Hi, I have one another doubt.
When I imprt excel sheet, there is a column for amount. In excel the amount is in £, but when inserted in database , there shows $ symbol. How is it changed automatically?

0

In exel sheet i used £12. But in database it shows only 12 or some times it is $12. pls tell me how to solve this?

thanks in advance.

I think in the database you should have only the number without any sign (provided that all the values are in same currency). You should get rid of the pound symbol i.e. using the mb_substr function, something like:

$trimmedAmount = mb_substr($amount, 1);

But I am not sure if this will work correctly since it depends on how the amount is read, what the encoding is and what the database column type for the amount is. Let me know the result.

Currenltly my database are values are like this.

         amountpaid
           12.98
           $10.50
           $12.10
           £11.50
           14.30
           £9.58
           .
           .
           .
           .

and i need to replace these values like,

           amountpaid
           £12.98
           £10.50
           £12.10
           £11.50
           £14.30
           £9.58
           .
           .
           .
           etc.

           pls tell me a solution...

Thanks..

waiting for your answer , pls help me.

I wrote code like this, but it add 2 £ ('££120'). code is,

$amount= mysql_real_escape_string("£59.99");

echo $first= $amount[1];

   if( ($first=="$")||($first=="£") ) {
        $amount     =substr($amount,1);
        $amount="£".$amount;
    }

It seems that the SQL statement the $sql variable does not get constructed properly. In the lines below you can see how it gets built up up to the VALUES part. But where are the actual values added to it then? Is there any more code you did not post?

Line  26: $sql = "INSERT INTO ".$table." (";
...
Line 205: $sql.= strtolower($column) . ",";
...
Line 208: $sql = rtrim($sql, ", ").", created_date ) VALUES ( ";
...

It is in the code that follows you should use the mb_substr function.

You can change the existing values in the database with a query like this:

UPDATE `test` SET amount = 
IF(
    SUBSTRING(`amount`, 1, 1) = '$', 
    CAST(SUBSTRING(`amount`, 2) AS DECIMAL(10,2)), 
    CAST(`amount` AS DECIMAL(10,2))
)

I am assuming that you have the amount column of type DECIMAL which I think is appropriate for money. You might have to create a temporary column if transformation can not be done in the same column.

Your code has a few errors:

$amount= mysql_real_escape_string("£59.99");

echo $first= $amount[1];

    if( ($first=="$")||($first=="£") ) {
    $amount =substr($amount,1);
    $amount="£".$amount;
}
  1. do the escaping at the end
  2. first letter has index 0: $first= $amount[0];
  3. I advise you not to store the pound sign into the database. The money values should be stored as DECIMAL

So in my view the code should be:

$amount= '$59.99';
$first= $amount[0];

// ASCII 36 = dollar sign, ASCII 163 = pound sign
if( ($first == chr(36)) || ($first== chr(163)) ) {
    $amount = substr($amount,1);
}

// store this value in database
$safe_amount= mysql_real_escape_string($amount);

You are welcome. If the problem is solved please mark the thread as solved. Happy coding.

This helped me a lot and I got great support from here. Currenlty I didnt update database via excel sheet, just updated the currency showing area only. Currenlty solved temporarily (working on another project now).
