[postgis-users] Problems with PHP and PostgreSQL/PostGIS

[Gerald Baumgartner]

I have renamed the tablename, but now there are other errors:

*Warning*: pg_query()
[function.pg-query<http://localhost/GpsDaten/function.pg-query>]:
Query failed: ERROR: column "date_start_fahrt" is of type date but
expression is of type integer at character 36 HINT: You will need to rewrite
or cast the expression. in *
C:\ms4w\Apache\htdocs\GpsDaten\GPS_Daten_einlesen.php* on line *103*

*Warning*: pg_query()

Query failed: ERROR: invalid input syntax for type numeric: "" in *
C:\ms4w\Apache\htdocs\GpsDaten\GPS_Daten_einlesen.php* on line *112*


php Code:

    $timestamp=time();
    $datum=date("d/m/y",$timestamp);
**
    if($z_eintraege==2)
    {
       $sql_befehl="INSERT INTO
fahrtenbuchtabelle(fid,date_start_fahrt,date_insert,strecke) VALUES
($z_eintraege,$datum,$datum,GeometryFromText('LINESTRING($breitengrad1
$laengengrad1, $breitengrad $laengengrad)',4326))";
       $res=pg_query($connection,$sql_befehl);
       $sql_befehl_select="SELECT max(FID) as fid from fahrtenbuchtabelle";
       $res_fid=pg_query($connection,$sql_befehl_select);
       $fahrtnummer=pg_result($res_fid,"fid");

    }
    if($z_eintraege>2)
    {
      $sql_befehl_append="UPDATE fahrtenbuchtabelle SET
strecke=AddPoint(strecke,GeomFromText('POINT($breitengrad
$laengengrad)',4326)) where fid='$fahrtnummer'";
      $result=pg_query($connection,$sql_befehl_append);
    }
