display specific number of characters

Recommended Posts

Hi

 

I am trying to work out how to display a specific number of characters in a echo row, the line looks like the following

echo "<td>" . $row->comments . "</td>";

Thank you in advance

 

Sorry I did look on Google but couldn't see a way to do it with the similar coding I have above

Use substr

 

Example

 

echo "<td>" . substr($row->comments, 0, 100) . "</td>";

Will only show the first 100 characters from the string stored in $row->comments

Thank you so much, works perfect

 

I just found another little issue when testing, the record date is being inserted into the mysql table as 00/00/0000 instead of the actual date, I am using datepicker, the INSERT query is below

// insert the new record into the database
				if ($stmt = $mysqli->prepare("INSERT repairs (customer_name, customer_email, customer_phone, computer_make, computer_model, technician, status, exrdate, exrtime, exstdate, exstime, deltype, comments) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)"))

Most likely MySQL is unable to interpret the date being in DD/MM/YYYY format. If you have set your column as date(time) format then MySQL requires dates to be inserted in YYYY-MM-DD format. So before inserting the date you need to convert it to use that format.

 

You can use PHP's DateTime object to do so


// your date value in DD-MM-YYYY format
$date = '4/10/2015';

// convert date to YYYY-MM-DD format
$dt = new DateTime($date);
$date = $dt->format('Y-m-d');

I renamed the $date to the name of $exrdate and it worked but it outputted the date as 10/4/2015 instead of 4/10/2015 and also it should be 4/11/2015 not 4/10/2015

 

also how do I get that to work for a second date as well as I have exrdate and exstdate
