MySQL insert error in PHP -


i've been trying code below execute, although no error appears, row not inserted when check result in database. there seems problem in passing $query $sql, because when echo same value of $query , add text $sql works fine.

any idea error ?

$i=3;  $query = '"'."insert data (id,qn,qi,cb,bk,qk)".""."values("."'".$i."','".$price[17]."','".$price[47]."','".$price[77]."','".$price[107]."','".$price[137]."')".'"';  echo $query;  $connect= mysql_connect("localhost", "urs" , "password") or die(mysql_error());  mysql_select_db("data", $connect);  $sql= $query;   mysql_query($sql,$connect)

the problem query has no space right before values make query syntactically incorrect far mysql goes. render when script runs:

insert data (id,qn,qi,cb,bk,qk)values(…);

mysql choke on query. instead, try version of query 1 space added before values:

$query = '"'."insert data (id,qn,qi,cb,bk,qk)".""." values("."'".$i."','".$price[17]."','".$price[47]."','".$price[77]."','".$price[107]."','".$price[137]."')".'"';

but said, concatenation makes 100% no sense & unnecessarily complex. i’ve cleaned & should work:

$query = "insert data (id,qn,qi,cb,bk,qk) values('$i','$price[17]','$price[47]','$price[77]','$price[107]','$price[137]');";

the key need understand double quotes in php allow string substation. no need concatenate degree did.

also missing semi-colon after mysql_query() should this:

mysql_query($sql,$connect);

so here cleaned version of code:

// set value `$1`. $i = 3;  // query. $query = "insert data (id,qn,qi,cb,bk,qk) values('$i','$price[17]','$price[47]','$price[77]','$price[107]','$price[137]');";  // set connection or die returning error. $connect = mysql_connect("localhost", "urs" , "password") or die(mysql_error());  // select database; mysql_select_db("data", $connect);  // run query or die returning error. mysql_query($query, $connect) or die(mysql_error());

but looking @ selecting database named data , inserting table within database called data well? correct? seems might have mixed idea of database & table double check that.

also note added or die(mysql_error()); after mysql_query($query, $connect). first or die(mysql_error()); covers errors in connection & not errors appear when query runs. if query has error, die error being returned.

that said, should explore using mysqli_* commands instead of mysql_* since mysql_* commands depreciated in php 5.3 5.4 , eliminated in php 5.5.

commonjs - How to write a typescript definition file for a node module that exports a function? -
