Hi

I have a script to update some records in a postgresql
database. when i do modify what i have to modify it
give me the warning:

Warning: pg_query() query failed: ERROR: pg_atoi:
zero-length string in
/var/www/html/adm/modificar_2.php on line 24
ERROR

this is line 24:
    $result = pg_query($db, $query);

this is modificar_2.php :

<?php
    $id = $_POST['id'];
    $titulo = $_POST['titulo'];
    $texto = $_POST['texto'];

    include 'db.php';
    $query = "UPDATE table SET titulo='$titulo',
texto='$texto' WHERE id='$id'";
    $result = pg_query($db, $query);
    if (!$result) {printf ("ERROR"); exit;}
    print ("Estes valores foram atualizados:<P> -
$titulo<BR>- $texto<BR>");
    pg_close($db);
?>

This is a snip from modificar_1.php

<?php
    $id = $_POST['id'];
    $titulo = $_POST['titulo'];
    $texto = $_POST['texto'];

    include 'db.php';
    $query = "SELECT id, titulo, texto FROM table WHERE
id='$id'";
    $result = pg_exec($db, $query);
    if (!$result) {printf ("ERROR"); exit;}
    $numrows = pg_numrows($result);
    $row=0;
    ?>
    <table border=0 style="border: 1px solid black;">
    <?php
        do {
        $myrow = pg_fetch_row ($result, $row);
        //print_r($myrow);
        print ("<tr><td>ID</td><td>$myrow[0]</td></tr>");
        print ("<tr><td>Título</td><td><input type=text
value=$myrow[1] name=titulo size=150
maxlength=150></td></tr>");
        print ("<tr><td>Texto</td><td><textarea cols=90
rows=20 value=$myrow[2]
name=texto>$myrow[2]</textarea></td></tr>");
        $row++;
    }
    while ($row < $numrows);
    ?>

Thanks in advance

Since this is the only thing that match an integer value, try to use
$id = $_POST['id'] + 0;
in case there is no id sent. You'll don't get any results [i hope there is
no id==0] but u'll don't have an error on your query.
Because id is integer try not to use *where id='$id'*. Use *where id=$id*
instead.

Do:
    print $query;
in your code to look at the query you send, atoi = ASCII to Integer.
It is failing to convert a null string into integer, your query is
malformed.

Hi

I have a script to update some records in a postgresql

give me the warning:

Warning: pg_query() query failed: ERROR: pg_atoi:
zero-length string in
/var/www/html/adm/modificar_2.php on line 24

this is line 24:

this is modificar_2.php :

<?php
$id = $_POST['id'];
$titulo = $_POST['titulo'];
$texto = $_POST['texto'];

include 'db.php';
$query = "UPDATE table SET titulo='$titulo',
texto='$texto' WHERE id='$id'";
$result = pg_query($db, $query);
if (!$result) {printf ("ERROR"); exit;}
print ("Estes valores foram atualizados:<P> -
$titulo<BR>- $texto<BR>");
pg_close($db);
?>

This is a snip from modificar_1.php

<?php
$id = $_POST['id'];
$titulo = $_POST['titulo'];
$texto = $_POST['texto'];

include 'db.php';
$query = "SELECT id, titulo, texto FROM table WHERE
id='$id'";
$result = pg_exec($db, $query);
if (!$result) {printf ("ERROR"); exit;}
$numrows = pg_numrows($result);
$row=0;
?>
<table border=0 style="border: 1px solid black;">
<?php
do {
$myrow = pg_fetch_row ($result, $row);
//print_r($myrow);
print ("<tr><td>ID</td><td>$myrow[0]</td></tr>");
print ("<tr><td>Título</td><td><input type=text

$row++;
}
while ($row < $numrows);
?>

Thanks in advance

print $query; You will get:
UPDATE table SET titulo='somthing',texto='text' WHERE id=''

And your pg version is >= 7.2, where you can not insert '' string in
integer type. cast $id as integer, '".($id+0)."' or intval or others.
